       SAMPLE-A: - Introduction : Why Java/j2ee is not a secure Programming Language?

     What   is the   Difference  betweeen   Java(Jdk1.8)  and  Oakjava7 ?

Brief  about  OakJava7  Divisions   and Doubtful  Faqs:-

==================================================================================

 Write Brief  about  OakJava7  Divisions   and Doubtful  Faqs:-

About OakJava7 Divisions

OakJava7 is  divided  into  6 types

i) Scroll Server with OakJava7 (.web) and OakJava7 (.ojava7)

ii) Scroll Server with  Java/j2ee and Java (jdk1.8) compiler 

(Note: Here Oakjava7 compiler is not used,instead of that Jdk1.8 compiler is used

with ScrollServer.Because  Hibernate, Mybatics ,Java Spring are written in Jdk1.8 

Thats why Oakjava7 compiler is not match with java/j2ee frameworks

Hibernate, Mybatics ,Java Spring ,and EJB.

so Jdk1.8 versions and  next versions of  Jdk1.8 will not be

supported to be used with Oakjava7 compiler.

Here Jsp ,and Servlet will not work in Scroll Server.

but EJB and JMS will work with Jdk1.8. 

You can see the sample for hibernate in SAMPLES SECTION.

ie) In Oakjava7 google site.

(Sample-2: Topic: Write   a JAVA7.0 program  with Scroll Program,

here Jdk1.8 compiler is focused).

(We advice Java Spring should optimize the source code.So Java(jdk1.8) 

professionals are permited to be used with most popular server which is Scroll Server.

)

iii) Scroll Server with (.java7) with Oakjava7 (OAKJAVA7.0) compiler

iv) Machine Learning and  data Science with  UserFriendly frameworks (OJ7UA).

v) Oakjava7  Advanced Samples with  (.web) and  Oakjava7 Console Application.

vi) OakJava7  with Remote X Application (Advanced Application) ( Not released now).

Doubtful FAQS?

1) Can oakjava7 compiler work  with  Jdk1.8 and java/j2ee frameworks ?

No.

2) Can Oakjava7 compiler compile Jdk1.8 programs ?

No, It will not accept jdk1.8 and other jdk1.8 versions.

3) Is Oakjava7  is the competitor of Java/J2ee?

No , Oakjava7 business is very different when compared

to Oracle business.

4) Is oakjava7 work as a Standalone application?

Yes, it will work without the help of Java/J2ee applications.

5) Is OakJava7 a high security Programming Language?

Yes.

Difference between Java(Jdk1.8) and  Oakjava7 ?

Both Java and Oakjava7 is used in webapplication and

console application.But Java follows cloudcomputing

Oakjava7 follows Remote-X Application.Oakjava7 is

not used to create a software like VB.net and

Java Swing. Oakjava7 is used only with java frameworks like hibernate

and Mybatics, it is not used with Java Spring ,the reason is Java Spring code is

very bulk. This Java Spring web/ standalone application

is very slow when compare to Node.js,Oakjava7(JAVA7.0).

Oakjava7 is invented in Dotweb and java(jdk1.6).Java Spring

takes more time to develop a webapplication when compared to OakJava7,Node.js.

And Oakjava7 has Advanced datastructures when compare to Java(Jdk1.8).

eg) Pipe,Bag,etc.Remember OakJava7 is not the competitor for Java,C#,

python,etc. OakJava7 is an interactive programming language. Java is

not a interactive programming Language.Oakjava7 is used in MachineLearning,

Datascience,mobile application,and single page application.

It supports obfuscation, Code Security, and it is Learnable.

Oakjava7 follows attractive and beautiful Userfriendly framework

(.oj7ua).Oakjava7 follows Shortest  function Statements.OakJava7 is

focus on Code Security.Oakjava7 is used with WNOSQL Database which  

provides high security...Oakjava7 is a standalone programming

language.That is without help of any available java frameworks 

Oakjava7 will able to create  webapplication,etc.Oakjava7 is

a Pure OOPS Programming Language. And Java/j2ee is not a

Pure OOPS Programming Language.Oakjava7 saves  time and  cost

and OakJava7 is a highest securable programming language.

Oakjava7 will compile and run the Oakjava7 program

at the same time. but Java(Jdk1.8) can't do it.

Demerits  of  Java/j2ee  Programming Language

Why Java/j2ee is not a secure Programming Language?

What ever java programs we write ,it is compiled to

.class file. So when you use JAD Decompiler what ever

program user write will be  converted to the source

code. So Security completly fails in 

Java,Jdk1.8 , and all the JDk versions.

for example)

Write a Mysql program listing the values from emp table.

MySQLCon.java

import java.sql.*;  

class MysqlCon{  

public static void main(String args[]){  

try{  

Class.forName("com.mysql.jdbc.Driver");  

Connection con=DriverManager.getConnection(  

"jdbc:mysql://localhost:3306/wil","root","Dove12345");  

//here sonoo is database name, root is username and password  

Statement stmt=con.createStatement();  

ResultSet rs=stmt.executeQuery("select * from emp");  

while(rs.next())  

System.out.println(rs.getInt(1)+"  "+rs.getString(2)+"  "+rs.getString(3));  

con.close();  

}catch(Exception e){ System.out.println(e);}  

}  

}  

After that when you compile the java program using Jdk1.8 or any java compiler

it produces .class file. So  when  the  hacker use JAD decompiler

jad <filename>.class

It will generate a source code for java/j2ee  in the form of  MysqlCon.jad what ever user code it.

You can see the code  as given below....  

MysqlCon.jad

// Decompiled by Jad v1.5.8f. Copyright 2001 Pavel Kouznetsov.

// Jad home page: http://www.kpdus.com/jad.html

// Decompiler options: packimports(3) 

// Source File Name:   MysqlCon.java

import java.io.PrintStream;

import java.sql.*;

class MysqlCon

{

    MysqlCon()

    {

    }

    public static void main(String args[])

    {

        try

        {

            Class.forName("com.mysql.jdbc.Driver");

            Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/wil", "root", "Dove12345");

            Statement statement = connection.createStatement();

            for(ResultSet resultset = statement.executeQuery("select * from emp"); resultset.next(); System.out.println((new StringBuilder()).append(resultset.getInt(1)).append("  ").append(resultset.getString(2)).append("  ").append(resultset.getString(3)).toString()));

            connection.close();

        }

        catch(Exception exception)

        {

            System.out.println(exception);

        }

    }

}

Note:

So all db connections and business logic is know to the hacker.

So writing the java program is useless,and hacker can easily steal

the data. Not only in Java , even in all the frameworks of

Java/J2ee , EJB, Servlet,Jsp,JMS,hacker can easily take  the data,db connections.

 That's  Why  Java/j2ee  fails completly in security side...

That's why  a New Interactive  programming language ,highly securable , more Advanced,

 Userfriendly Programming  Language   which  come in to the picture.

Which   is known  as   OakJava7(JAVA7.0)  Programming Language, which  is  created   in

Dotweb3.0(Advanced Programming Language)  and  Java(Jdk1.6)   by Wilmix Jemin .J.

What   is  the   Expansion   of    OAKJAVA7(JAVA7.0)   Programming Language.

Expansion  of  JAVA7.0  is

J  stands  for Jemin   , A stands   for Advanced , V stands  for  Virtual , and  A  stands for

Application   , 7 -> stands  for   wise  Programming  Language.

Note: Developers must  know  the  difference  between  OakJava7   and Jdk1.8. Then only

You  can  easily  study about  Oakjava7 (JAVA7.0).

=========================================================================================

Java7.0 OOPS and Java7.0 Exception 

===================================

Note:  For  Java7.0- Java oops follow corejava oops ,  i has left  a  choice for

the  developers  to  do  their own assignment related  to   Java7.0 - Java oops..

JAVA7.0 OOPS

==============

First  Part  of JAva7.0 oops  is  simillar  to  C# oops  for  Oakjava7 <filename>.web

and  Second  part  of Java7.0 opps  is  simillar  to  Core Java  ooops..

Java7.0 oops  is  designed  in such  a way   that   Java / C#  professionals  can

easily  follow  it. Due  to this  Java7.0  is  otherwise  known  as  Interactive  Programming

Language.

JAVA7.0 Exception

=================

JAVA7.0  Exception is  simillar  to  java  and  C#  exception.

Java7.0 Excpetion  is  designed  in such  a way   that   Java / C#  professionals  can

easily  follow  it. Due  to this  Java7.0  is  otherwise  known  as  Interactive  Programming

Language.

Now  I explain  a   samples related   to Java7.0-OakJava7.0 <filename.web> oops which  is  given  below..

Properties  in Java7.0

=======================

A property is like a combination of a variable and a method, and it has two methods: a get and a set method.

The Name property is associated with the name field. It is a good practice to use the same name for both the property and the private field, but with an uppercase first letter.

The get method returns the value of the variable name.

The set method assigns a value to the name variable. The value keyword represents the value we assign to the property.

Programs2.web

==============

<WEB>

<PACK> ConsoleApp28934

{

<CLASS> Person

{

  private string name; // field

  public string Name   // property

  {

    get { return name; }

    set { name = value; }

  }

}

<CLASS> Java7oops

    {

           public void main()

        {

 Person myObj = new Person();

    myObj.Name = "BRITO";

    <PRINTLN>(myObj.Name);

        }

    }

}

Output:

=======

BRITO

===========================================================================

Inheritance  in Java7.0

===========================

Inheritance  means  parent  class  inherits  the  properties  of  child  class

but  here  inheritance  can  be  achieved  by using  ":" operator.. 

Programs2.web

=============

<WEB>

<PACK> Inheritance

{

<CLASS> Vehicle  // base <CLASS> (parent) 

{

  public string brand = "Ford";  // Vehicle field

  public void sound()             // Vehicle method 

  {                    

    <PRINTLN>("ook, ook!");

  }

}

<CLASS> Car : Vehicle  // derived <CLASS> (child)

{

  public string modelName = "Mustang";  // Car field

}

<CLASS> Java7oops

    {

           public void main()

        {

  Car myCar = new Car();

    // Call the sound() method (From the Vehicle class) on the myCar object

    myCar.sound();

    // Display the value of the brand field (from the Vehicle class) and the value of the modelName from the Car class

    <PRINTLN>(myCar.brand + " " + myCar.modelName);

        }

    }

}

OUTPUT

=======

ook, ook!

=================================================================

Polymorphism in Java7.0

==========================

Polymorphism means "many forms", and it occurs when we have many classes that are related to each other by inheritance.

Polymorphism uses those methods to perform different tasks. This allows us to perform a single action in different ways.

Now we can create Pig and Dog objects and call the animalSound() method on both of them:

Programs2.web

==============

<WEB>

<PACK> Polymorphism

{

<CLASS> Animal  // Base <CLASS> (parent) 

{

  public void animalSound() 

  {

    <PRINTLN>("The animal makes a sound");

  }

}

<CLASS> Pig : Animal  // Derived <CLASS> (child) 

{

  public void animalSound() 

  {

    <PRINTLN>("The pig says: wee wee");

  }

}

<CLASS> Dog : Animal  // Derived <CLASS> (child) 

{

  public void animalSound() 

  {

    <PRINTLN>("The dog says: bow wow");

  }

}

<CLASS> Java7oops

    {

           public void main()

        {

 Animal myAnimal = new Animal();  // Create a Animal object

    Animal myPig = new Pig();  // Create a Pig object

    Animal myDog = new Dog();  // Create a Dog object

    myAnimal.animalSound();

    myPig.animalSound();

    myDog.animalSound();

        }

    }

}

Output:

=======

The animal makes a sound

The animal makes a sound

The animal makes a sound

===========================================================================

Java7.0 Abstraction

=====================

Abstaction  is  defined  as  process  of  hiding  all  internal  details   from  the   outside world

and  provide  only  functionality   to  the  user.

Abstraction  can be   achieved  by using  abstract keyword and  Abstract methods..

The abstract keyword is used for classes and methods:

Abstract class: is a restricted class that cannot be used to create objects (to access it, it must be inherited from another class).

Abstract method: can only be used in an abstract class, and it does not have a body. The body is provided by the derived class (inherited from). 

Programs2.web

==============

<WEB>

<PACK> ABSTRACTION

{

abstract <CLASS> Animal

{

  // Abstract method (does not have a body)

  public abstract void animalSound();

  // Regular method

  public void sleep()

  {

    <PRINTLN>("Zzz");

  }

}

// Derived <CLASS> (inherit from Animal)

<CLASS> Pig : Animal

{

  public override void animalSound()

  {

    // The body of animalSound() is provided here

    <PRINTLN>("The pig says: wee wee");

  }

}

<CLASS> Java7oops

    {

           public void main()

        {

Pig myPig = new Pig(); // Create a Pig object

    myPig.animalSound();  // Call the abstract method

    myPig.sleep();  // Call the regular method

        }

    }

}

Output:

=======

The pig says: wee wee

Zzz

===========================================================================

Interface in Java7.0

=======================

Java7.0  doesnot  support  multiple Inheritance but multiple Inheritance  can  be  achieved  

using  interface  in Java7.0. If  you  are  using  multiple interface  separate  the  interfaces  by

comma. eg)  Interface name is toys, Interface name  in  electronics

so  seperate the  two  interface  toys,electronics 

ie) <CLASS> Things : toys, electronics  in  your  Java7.0  Program.

Notes on Interfaces:

=====================

Like abstract classes, interfaces cannot be used to create objects (in the example above, it is not possible to create an "IAnimal" object in the Program class)

Interface methods do not have a body - the body is provided by the "implement" class

On implementation of an interface, you must override all of its methods

Interfaces can contain properties and methods, but not fields/variables

Interface members are by default abstract and public

An interface cannot contain a constructor (as it cannot be used to create objects)

Programs2.web

==============

<WEB>

<PACK> interfaceexample

{

// Interface

interface IAnimal 

{

Enumeration  in  Java7.0

=========================

An enum is a special "class" that represents a group of constants (unchangeable/read-only variables).

To create an enum, use the enum keyword (instead of class or interface), and separate the enum items with a comma.

Programs2.web

==============

<WEB>

<PACK> enumexample

{

// Interface

<CLASS> Program

{

  enum color

  {

    red,

    black,

    green

  }

           public void main()

        {

color myVar1 = color.red;

    <PRINTLN>(myVar1);

        }

    }

}

Output

======

red

Exception  in Java7.0

=====================

Exception  is  an abnormal condition  that  arise  during  the  code   sequence  at  runtime.

It  can be  achieved  by  using   <TRY> and  <CATCH>  or <Finally> block.

<Finally>  block  is  not  mandaltory, it  is  optional.  

when  you  specify  <Finally> block statements in Java7.0 , if the exception  arise  or

not  the  <Finally> block statements  will be get  excecuted..  

Programs2.web

==============

<WEB>

<PACK> exceptionexample

{

<CLASS> Program

  {

           public void main()

        {

 <TRY>

      {

        int[] myNumbers = {15, 21, 123};

        <PRINTLN>(myNumbers[10]);

      }

      <CATCH> (Exception e)

      {

        <PRINTLN>("Error.... "+e);

      }  

     <Finally>

      {

        <PRINTLN>("The Finally block  is  executed...");

      } 

    }

        }

    }

Output:

=======

Error.... System.IndexOutOfRangeException: Index was outside the bounds of the 

array.

   at exceptionexample.Program.Main(String[] args)

The Finally block  is  executed...

===========================================================================

UserDefinedException in  Java7.0

==================================

The throw statement allows you to create a custom error.

The throw statement is used together with an exception class.

in this  eg)  Arithmetic Exception  is  indicated  by  keyword <Arithmetic> in Java7.0..

So  you  had  to create   throw  new  Exception in  your method for   creating

User defined  exception  in Java7.0.

Programs2.web

==============

<WEB>

<PACK> userdefinedexception

{

<CLASS> Program

  {

 static void checkAge(int age)

    {

      if (age < 18)

      {

        throw new <Arithmetic>("Access denied - You must be at least 30 years old.");

      }

      else

      {

        <PRINTLN>("Access granted - You are old enough!");

      }

    }

           public void main()

        {

       checkAge(20);

    }

        }

    }

Output:

=======

Access granted - You are old enough!

                    SAMPLE -16 :  STEPS FOR  JAVA7.0 Program ,compile  and  execute it

=================================================================================================

What  are  the  steps  to  write OakJava7 <filename.web>  program

and  how  to  configure  it and  Compile and  run   Java7.0 -> <filename.web> program  ?

STEPS FOR  JAVA7.0 Program

==========================

Step-1:  Write  a  OakJava7 <fiename.web>  in  a  file <fiename.web>  at Oakjava7 directory..

======

example)

HelloWorld.web

<WEB> // Represents to  load  oakjava7  default System packages.

<PACK> Example // <PACK> means  namespace  in  C#  or package  in java

{

    <CLASS> Program // <CLASS> means  class keyword in java or  c#

   {

      public void main() // Main function  of  oakjava7 program

      {

//<PRINTLN> means  printing  the  string  "HELLO WORLD!  MY First Java7.0 Program"  at windows command or Java7Shell prompt..

<PRINTLN>("HELLO WORLD!  MY First Java7.0 Program");

      }

   }

}  

Step-2:  Create  a  Blank file  <filename.web.lib> , <filename.web.obj> in  Oakjava7/outputs directory.

when  you   used only with  Command Prompt.But  when  you  use  Java7ShellPrompt 

and  compile the  files  using  javac7 <filename>.web. Java7ShellPrompt  will provide  autoconfiguration and  generates  .exe  at  output  directory..After  that Java7ShellPrompt  command  javac7 <filename.web>  will automatically  copy   from  /oakjava7/outputs directory   to   /oakjava7  directory  with  filename.exe  and  now  it  is  prepared for  the  developers  to     Execute the  Program  in  Java7Shellprompt  using  RunJava7.

So  there  is  no need  for  manual  configuration  for  Java7ShellPrompt  , Java7ShellPrompt  will  take  care..  

Step-3:  For  Command prompt , open  the   command prompt

and  compile the  files  using  javac7 <filename>.web

it  will  generates  .exe  at  output  directory..

and  copy  that  <filename.web>.exe  in  Oakjava7 directory

and  execute  <filename.web>.exe  in  command prompt

or  Java7Shell prompt  you  will  get  the  output  as

given below...

 Output:

=======

HELLO WORLD!  MY First Java7.0 Program

                      SAMPLE -17 :  How to Debug a errors in Java7.0  using Java7ShellPrompt During  compile /Run time ?

=================================================================================================

How to Debug a errors in Java7.0  using Java7ShellPrompt During  compile /Run time ?

Compiletime Error

==================

a)  If  you not  created a  java7  file  but  compile using  javac7 <filename.java7> in  a Java7ShellPrompt.

It will  display  the  screen shot  as  shown  below..

b) But  if you  created a  java7 file  but  compile using  javac7  <filename.java7> in a  Java7ShellPrompt.

it  will not  show  any error  in Java7ShellPrompt. But  if  you compile  using  javac7 <filename.java>

results  in  error which  is  "SystemIndexOutOfRangeException". that means it will not accept  .java  extension.

it   will  accept only  .java7  extension .

c)  If  you not  created a  java7  file  but  compile using  javac7 <filename.web> in  a Java7ShellPrompt.

It will  display  the  screen shot  as  shown  below..

d)   But  if you  created a  java7 file  but  compile using  javac7 <filename.web> in a  Java7ShellPrompt.

it  will not  show  any error  in Java7ShellPrompt. but it will  display  the  screen shot  as  shown  below..

Runtime Error

=============

e)  If  you not  created a  java7  file    but  run using  java7 <filename> in  a Java7ShellPrompt.

It will  display  the  screen shot  as  shown  below..

f) If  you   created a  java7  file and  compile without no error and if  there  is  runtime  error occur. But When we run using  

java7 <filename>  in  a Java7ShellPrompt.It will  display  the  screen shot  as  shown  below..

g)  If  you not  created a  oakjava7(.web)  file and compile with error  and  run using  RunJava7 <filename> in  a Java7ShellPrompt.

it  will  display  a  message box  that  "System cannot  find the  file  specified" in  a  Java7ShellPrompt.

h) If  you   created a  java7  file and  compile without no error and if  there  is no runtime  error occour. But When we run using 

 java7 <filename>  in  a Java7ShellPrompt.It will  display  the  screen shot  as  shown  below..

i) If  you   created a  oakjava7(.web)  file and compile without error  and  run using  RunJava7 <filename> in  a Java7ShellPrompt.

it  will  display  the  screen shot  as  shown  below..
