I recently completed a "fun" program where it asks the user questions and outputs answers. I submitted it and my professor said all was great, except he wanted me to implement methods into the program. I have NO idea how o do the methods. Can someone use my code to give me an example or something, or at the very least help me figure it out?

He told me to use a for loop instead of a do while, and told me to use this method.

boolean gotItRight;
gotItRight = doQuestion("Q: Polar bears...",
                   "A: ...", "A: ...", TRUE_NUM);
if(gotItRight) count++;
gotItRight = doQuestion("Q: This quiz...",
                    "A: ...", "A: ...", FALSE_NUM);
if(gotItRight) count++;

This is my program code:

import java.util.*;
public class Fun {
    /**
     * I thought of doing a trvia question type program.
     * The questions I entered, I thought were interesting. 
     * For being a pretty pathetic programmer, I would say I did a good job.
     * It's not up to me though. So...
     * 
     * Please have mercy on my soul.

I'm not asking you guys to do my HW, but I just want to know how to implement the method so I can get started.

make methods which contains the question a method for each question
and return true if correct and false if wrong and other method to calculate the result

Look at the suggested code. It's calling a method, passing a question, two answers, and a last param showing which answer is correct.
You need to create the method with those 4 parameters so it shows the Q and the A's, gets the reply, and finally returns true or false depending on whether the user got it right or not. Then you can just call that method for each actual question without repeating all the code.
