Java Tutorials:
Udemy: (you must be logged in to Udemy for video links to work) Main Udemy course link
Introduction and Installation (9:38) some good information about Java, Eclipse, JDK, and JRE but you don't need to follow along, it is better to just download Eclipse and JRE from ninite.com
What Java Is and How it Works (12:38) Java language, text / code .java files, javac or green run button creates binary .class files, JVM part of JRE is an extra layer that allows same code to run on all computers
Getting a Job... (18:59) begin with the end in mind, job sites
How to Get the Most Out of This (Udemy) Course (9:24) create programs!, learn to touch type, create programs you are interested in, break it down into steps
A Hello World Program (4:46) creating a new project and class, check box for void main, delete comments, sysout Ctrl Space, Ctrl D to delete line

A class is code.
A class is the blueprint from which individual objects are created.
Objects are instances of a class.
Objects have two characteristics: state (fields) and behavior (methods).
Benefits of objects:
Modularity
Information-hiding
Code re-use
Pluggability and debugging ease
A package is a namespace that organizes a set of related classes and interfaces. Conceptually you can think of packages as being similar to different folders on your computer.

Java, Exercises
Why Learn Java?
Java ranks #1 in the PopularitY of Programming Language (PYPL) index and the TIOBE index.
"Knock, knock"
Technology Requirements:
Java programs can be written on some web sites like programmr.com and TutorialsPoint but additional features are available in IDE programs like Eclipse, NetBeans, IntelliJ IDEA, or others. You are encouraged to experiment with multiple IDEs but Eclipse will be the primary one used in the course. IDEs require the installation of the JDK.
There are keyboard shortcuts and code templates (text expansions) available to help with coding in most IDEs. NetBeans Keyboard Shortcuts In Eclipse, select Window/Preferences, Java/Editor/Templates. (use Ctrl + Space)
JDK (Java Development Kit)
a specific SDK (Software Development Kit)
a collection of programming tools, such as compilers and debuggers for developing applets and applications
includes JRE and JVM
compiles *.java files into *.class files
only needed by programmers
JRE (Java Runtime Environment)
the minimum requirements for executing a Java application; it consists of the JVM, core classes, and supporting files
installed on almost all personal computers and many other devices (includes the Java plugin)
the JRE does not contain tools and utilities such as compilers or debuggers for developing applets and applications
Also referred to as: Java software for your computer, the Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, Virtual Machine, Java VM, JVM, VM, Java plug-in, Java plugin, Java add-on or Java download.
JVM (Java Virtual Machine)
an abstract computing machine that enables a computer to run a Java program
doesn't understand the Java language
works with byte code in *.class files created by compiling *.java files
interprets the byte code into the machine code
Java is portable because there are specific implementations of the JVM for different systems (Windows, Linux, MacOS, etc.)
