How to create a method that repeats a function?

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

You could add a while loop before the generation of the random numbers that would repeat until answer== "exit". Something along those lines would work fine

You should put a break; statement in the bottom else loop and put everything from your public static void declaration in an "infinite" for loop. When the user inputs an incorrect answer, the program will go to the else loop and break. Otherwise, it will keep on repeating in the "infinite" for loop. Here is a sample code showing what you could do.

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)
{   

boolean loopTest = false;

while (loopTest= true)
{

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 the 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");
  break;
}
while (answer != result);
}

}
}
