How to create a method that repeats a function?

Question

Hello everyone I am new to the site and this is my first question from my Java programming class. I have to create a program that asks a math question and tells the user if he is right or wrong, but the requirements also state that I need to create a method that generates a new question if the first question is correct, so when the computer asks what is 5 times 5 and the user inputs 25 the method should generate two new random numbers and ask the user for a result.

This is my code so far. I don't expect the answers as this is a school assignment but if anyone could give a direction it would be greatly appreciated it as this is my first java college course.

import java.security.SecureRandom; //program uses class SecureRandom
import java.util.Scanner; //program uses class Scanner

public class CAI 
{
public static void main(String[] args)
{   

    System.out.println("Alex - Assignment 4\n");

    //create Scanner for input from command window
    Scanner input = new Scanner(System.in);

    //randomNumbers object will produce secure random numbers
    SecureRandom randomNumbers = new SecureRandom();

    //generates two random numbers from 1 to 9 excluding 0
    int random1 = 1+ randomNumbers.nextInt(9);
    int random2 = 1+ randomNumbers.nextInt(9);

    int answer; // declares answer from user

    //calculates real result of first integer times second integer
    int result = (random1 * random2);

    //display generated integers
    System.out.printf("What is %d times %d?\n",random1, random2);

    do 
    {
    answer = input.nextInt(); //keeps taking answer from user if wrong
     if(answer == result) //if correct answer then print very good!
      System.out.println("Very Good!");
     else // if wrong answer then print no please try again
      System.out.println("No. Please try again");
    }
    while (answer != result);
 }

I think you have the basic way that your loop statements work mixed up. A do statement is going to execute its block of code once and wont inherently loop on its own. A while loop will repeat until you tell it to stop. So without telling you exactly how to structure your assignment ;) you should look at those two things. But your code does compile and does do one run through of what you want it to do. So this means that the problem you have is in the logic aspect of your code. This means that the computer doesn't understand based on the structure of your code when to execute the sections of your code.

So my advice is to try writing it out in plain English first (pseudocode) that way you can work out how the logic of your program should run and then translate it into code. Sometimes just saying "I want x to happen when y. But I only want this to happen if event z has happened." can help you understand logical how something has to work.

Best of luck
