Please let me know if this worked like you wanted it to and if there are any thing unclear, let me know and i will try my best to help you out. eventhough, i am far from an expert (done java for about a year now).

Im trying to create a quiz so that it asks you a question of a multiple choice, though i cant seem to figure out on how to loop it back to the incorrect question..Im still kind of new to java programming and my understanding is unfortunately not so good..

It is a simple quiz question that asks the user "Do you think my dog is cute?" If they answer "Yes," the dog Woofs and smiles. If they say "no" He growls at them and frowns.If a different answer is given, "What? Please try again" is printed.

I want my code to output a question for 20 seconds and ask for an input for the answer and when the time is up, question number 2 should show up. I am stuck on what should I do to have that, a reference is enough, I just don't know what to read on about, I am using java.util.Timer and TimerTask.

ExecutorService but i only see examples that it shutsdown after the timer, i need to post another question after the timer ends, not shotdown the program since i need a time limit for each question and not a timer for the whole quiz.

I am creating a quiz in Android Studio. My testActivity.java has a pager adapter in it which displays 3 fragments(questions). When I press "End" button a new activity called "Result.java" starts. It shows how many correct answers I have and did I pass the test. I have another button in my Result activity, which once pressed should open up the same test that the person has just did but with explanations below each question. I also want that the checkboxes that the person have checked during the test would be checked when the results are shown. How can I do that?

I have an assignment to do so this assignment is a simple quiz program that the user need to answer the 10 questions from the database (but i currently have 3 questions displaying all in one frame because i used jscrollpane..). At the end of the quiz i'd like to display the score of the user but instead to display "3 out of 3" it displays "6 out of 3"..and i am really trying my best for almost 3 days to figure out why.

Instructions: For each question,choose the single best answer.Make your choice by clicking on its button.You can change your answers at any time.When the quiz is graded, the correct answers will appear in the box after each question.

Today, I'll walk explain the steps needed to make your very own quiz game using the Java programming language. Regardless of whether or not you have prior programming experience, I'm sure this short project will help you gain a better understanding of Java and further hone your skills.

It takes some grind to ace a Java interview. So, how will you swim through your advanced java interview questions? Or, how will you find the bright minds who can answer core java interview questions like they were primary math questions? Whether you are an experienced Java developer or a recruiter seeking the best Java developers, we encourage you to go through the following docket of Java interview questions. We hope it will help you find your dream job or dream candidate.

In this quiz and worksheet, you'll answer multiple-choice questions about singly linked lists in Java and how they are created. The questions included here concern topics such as when it would be appropriate to create a linked list in Java and the code needed to change a linked list in an example.

Stack memory is the portion of memory that was assigned to every individual program. And it was fixed. On the other hand, Heap memory is the portion that was not allocated to the java program but it will be available for use by the java program when it is required, mostly during the runtime of the program.

Now for the question: Is java a completely object-oriented programming language? We can say that - Java is not a pure object-oriented programming language, because it has direct access to primitive data types. And these primitive data types don't directly belong to the Integer classes.

It is because abstract classes are incomplete classes that need to be inherited for making their concrete classes. And on the other hand, the final keywords in class are used for avoiding inheritance. So these combinations are not allowed in java.

And for calculating this, an extra arithmetic operation has to be performed. And consider the case where millions of addresses need to be calculated, this causes complexity. So to avoid this, ) the index array is supported by java.

This is a java tricky interview question frequently asked in java interviews for the experienced. The output will be like this because, when the java program is compiled and gets executed, then there are various steps followed for execution. And the steps are -

System.out.println() is used to print the message on the console. System - It is a class present in java.lang package. Out is the static variable of type PrintStream class present in the System class. println() is the method present in the PrintStream class.

In other words, if there is 1 supplementary character of 2 units, the length of that SINGLE character is considered to be TWO - Notice the inaccuracy here? As per the java documentation, it is expected, but as per the real logic, it is inaccurate.

Your PersonalityQuiz program will take just one command-line argument: a string that is the name of the file containing the quiz information. The quiz instructions (questions, titles, scoring details, etc.) are stored in separate text files ending in .quiz so that we can use our program to load different quizzes (depending on the text file used). Make sure to read the command-line argument as the first thing you do and store it in a variable called filename.

The .quiz files all start in the same way: one line containing the title of the quiz, followed by three lines that contain the description that the quiz taker will see when starting the quiz. These lines will be read verbatim from the file and then printed directly to the user. You can assume that none of these first four lines will be empty.

The next unread line in the quiz file contains two numbers: the total number of possible outcomes from the quiz and the number of questions in the quiz, respectively. For example, in LilaOrLenu.quiz, this line looks like:

Try running java PersonalityQuiz and giving answers 0, 1, and 0. At the end, you should see 0 1 0 get printed! If you provide three different answers, you should see those numbers printed in the same order.

After the scoring guide, we have the results messages. There will be one line per possible outcome in the quiz, and your job after scoring will be to print out only the line representing the outcome that has accumulated the highest score.

If the first line of the scoring guide reads 0 1 2, we would create an array called scoringGuide with the values {0, 1, 2}. To look up what the quiz taker answered for the first question, we would look at position 0 of the answers array. This would be the value 1, so then we would look up which outcome gets a point for this answer by visiting scoringGuide[1], which has the value 1. This means that outcome 1 gets a point, so we could navigate to scores[1] and increment the value stored there.

In this example, the class MyClass belongs to the com.example package. To run this code, you would need to save it in a file called MyClass.java and compile it using the javac command. You would also need to specify the package name when running the code using the java command: java com.example.MyClass.

Java naming convention is a rule to be followed for naming your identifiers such as package, variable, method, and constants. These conventions are supported by many Java communities such as Netscape and Sun Microsystems and mostly all the fields of java programming are given according to Java naming conventions.

Yes, there is a class called Constructor class available in Java. The purpose of the Constructor class is to get the internal information of the constructor in the class. It is present in java.lang.reflect package.

By using the Math.random() method we can generate random numbers in Java ranging from 0.1 to less than 1.0. Moreover, the random numbers can be generated by using the Random class present in java. util package.

A wrapper class converts java primitives into objects. So a primitive wrapper class is a wrapper class that encapsulates, hides or wraps data types from the eight primitive data types so that these can be used to create instantiated objects with methods in another class or in other classes. The primitive wrapper classes are found in the Java API.

Applets are executed within a java enabled browser, but a Java application is a standalone Java program that can be executed outside of a browser. However, they both require the existence of a Java Virtual Machine (JVM). Furthermore, a Java application requires a main method with a specific signature, in order to start its execution. Java applets do not need such a method to start their execution. Finally, Java applets typically use a restrictive security policy, while Java applications usually use more relaxed security policies.

The JDBC Driver provides vendor-specific implementations of the abstract classes provided by the JDBC API. Each driver must provide implementations for the following interfaces of the java.sql package: Connection, Statement, PreparedStatement, CallableStatement, ResultSet and Driver. e24fc04721
