How to create quiz in java

Quiz program implemented in java [duplicate]

I am still working on printing questions. 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.

Quiz program implemented in java [duplicate]

I am writing a program to implement «quiz» in Java 8

import java.util.Scanner; import java.util.*; class Question < String question; int no; HashMapoptions; String correctanswer; public static void q_no() < System.out.println("enter a question no"); int num; Scanner no = new Scanner(System.in); num = no.nextInt(); >public static void set_question()

Here in setting options, I am getting errors in the while loop while implementing the program.»runtime errors thrown as NullPointerException s»

 public void set_options() < System.out.println("enter options"); int count = 1; String q; Scanner str = new Scanner(System.in); while (count < 5) < System.out.print("set option" + count); q = str.nextLine(); options.put(count, q); count++; >> public void set_correctanswer() < System.out.println("enter correct answer"); Scanner d = new Scanner(System.in); String ans = d.nextLine(); >public static void marks() < >> 

Here you would write your questions to an ArrayList and display them in a second question.

class Quiz < ArrayListlist = new ArrayList<>(); public ArrayList adding(Question q) < list.add(q); return list; >public void show() < int g = list.size(); int count = 0; while (count < g) < list.get(count); >> > 

In menu, if you choose 1 you get add questions or type 2 you could get a list of questions. I am still working on printing questions.

This is a poor implementation.

You have System.out calls to interact with a user inside your Question class.

A better idea would be to move user actions out into a driver class .

You don’t follow java coding standards or JavaBean standards. You will surely come to grief over both. Should be setCorrectanswer() , not set_correctanswer() .

Making a quiz with timer on java

I am making a timed quiz where there should be a timer on each question.

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.

if(seconds <=20) < question1(); >else if (seconds<=40||seconds>=21) < new ProcessBuilder("cmd","/c","cls").inheritIO().start().waitFor(); question2(); >

while(seconds <=20)< question1(); >while(seconds<=40||seconds>=21) < new ProcessBuilder("cmd","/c","cls").inheritIO().start().waitFor(); question2(); >

This is what my question method looks like.

public static void question2(String. args) throws IOException, InterruptedException < System.out.println(""); System.out.printf("%72s\n","QUIZ FOR PHILIPPINE HISTORY"); System.out.println(""); System.out.printf("%64s\n","Question #2"); System.out.println(""); System.out.println("\t\t\t\t\t WHO DISCOVERED PHILIPPINES?"); System.out.println("\n\t\t\t\t\t\tA. Fernando Magellan"); System.out.println("\t\t\t\t\t\tB. Ferdinand Megallan"); System.out.println("\t\t\t\t\t\tC. Ferdinand Magellan"); System.out.println("\t\t\t\t\t\tD. Fernando Poe"); System.out.println("\n\t\t\t\t\t\tTYPE YOU ANSWER HERE: "); char answer2 = a.nextLine().charAt(0); switch (sagot2) < case 'B': case 'b': score++; seconds = 21; System.out.print("You are CORRECT!"); break; default: System.out.print("You are WRONG"); seconds = 21; break; >> 

This is the beginning of my code plus the timer and timertask.

import java.util.Timer; import java.util.TimerTask; import java.util.Scanner; import java.io.IOException; public class q2 < static int seconds = 0; static Scanner a=new Scanner(System.in); static Timer timer = new Timer(); static int number = 1; static int score = 0; public static void mema()< TimerTask task = new TimerTask () < public void run() < seconds++; System.out.print(seconds); >>; timer.schedule(task,1000,1000); > 

I also tried using this but it doesnt do the other method after 5 seconds.

long start = System.currentTimeMillis(); long wait = 5000; long end = start + wait; long end1 = end + wait; while (System.currentTimeMillis() < end) < question1(); >while (System.currentTimeMillis() < end1 || System.currentTimeMillis() >end)

Various things that you did make your code more complicated then it ought to.

First of all, avoid fixing details such as «this is the first question» versus «this is the second question».

Instead: focus on basic elements that you need. In your case: you want to display a question for a certain amount of time. Afterwards, the program should either display another question — or probably give a summary and end.

Thus: write a class/method that simply puts up a question and then waits. And then think how you could re-use that code to put up any number of questions in sequence.

For the «timing»: given the fact that you are a beginner, I would recommend you to not go «fully multi-threaded» (meaning: tasks, and schedulers) at this point. Instead, «waiting for some time» can easily be achieved via

• getting the currentTime
• endTime = currentTime + 20 sec
• looping until that endTime is reached

Thing is: you learn programming by exploring your options and trying many things. Thus I gave you hints — not code.

Building a test program in java

Hello I am new to Java and NetBeans and am in Advanced classes in which my classes are 5 weeks long, so it is a lot to learn a new code language in 5 weeks. Anyways I have an assignment to Create a class named Movie that holds a movie name and rating. Provide methods to get and set both the movie name and rating. Create a class named TestMovie that creates three Movie instances with different values for name and rating and prints the information about each movie. I have done the code and it is passing the build fine but my professor wants a screen shot of the program working and running but I can’t get NetBeans to bring that up. The chapter on building the test project was ripped out of my book. Can I get some help or pointers here is the code I have done:

package movie; /** * * @author Jason */ public class Movie < String movieRating; public Movie(String rated, String mtitle) < this.mrating = rated; this.title = mtitle; >public void setRating(String Rating) < movieRating = Rating; >// Get the rating public String getRating() < return movieRating; >public void setTitle(String title) < this.title = title; >public String getTitle() < return title; >@Override public String toString() < return "Movie" + " title=" + getTitle() + " rating=" + getRating(); >public static void main(String args[]) < Movie mv = new Movie("", ""); mv.toString(); >private String title; private String mrating; > 

You can just run a test on the console, that is, create a MovieTest class with only a main method and create three instances/objects of Movie ( Movie m1, m2, m3; OR Movie[] movies; ). Assign them values either in the constructor or with the set methods then print them out with the method print or println in System.out .

Something along the lines of:

Then end by screenshooting the results.

As an alternative to the other answers suggesting printing the output to the console, with the Netbeans’ UI editor you can easily create a window with a label showing the result, which makes it slightly more fancy.

You can get details on how to this here. Here’s an image from that page:

The full working code is here. As you can see, it’s just a few extra lines.

Your application prints no output, because you invoke toString(), but you don’t print the result of it.

An example to create 3 Movie instances with data, print them out, and then make a screenshot of your console app.

public static void main(String args[]) < ListmovieList = new ArrayList(3); Movie mv1 = new Movie("very Good", "Testfilm 1"); movieList add(mv1); mv1 = new Movie("good", "Testfilm 2"); movieList add(mv1); mv1 = new Movie("not good", "Testfilm 2"); movieList add(mv1); for (Movie m : movieList) < System.out.println(m.toString()); >>
