y/n loops?

[Jacob Smithenson]

Hello! I've got an assignment to take this code (done for a previous assignment, you insert a starting number, upper bound, and step size, and it provides a list of numbers) and put it into a loot that at the end asks you if you'd like to do it again, and entering a y starts over (obviously) and n ends the program. I have absolutely no idea how to make y continue it. I understand that something boolean would make the most sense, but I'm only about a week and a half into the course so I really have no idea other than that.( Also, it is supposed to prompt an error message if the upper bound is lower than the starting number). Here is the code:

import java.util.Scanner;

public class UpperBound {


    public static void main(String[] args) {
        int num1;   // starting number
        int num2;   // upper bound
        int num3;   // step size
        
        // Open up the keyboard for user input
        Scanner keyboard = new Scanner(System.in);
        
        System.out.println("Enter starting number:");
        num1 = keyboard.nextInt();
        System.out.println("Enter upper bound:");
        num2 = keyboard.nextInt();
        System.out.println("Enter step size:");
        num3 = keyboard.nextInt();
        
        int count=0;
        for(int i=num1; i<num2; i+=num3) 
        {
            if(count!=0 && count%10==0)
                System.out.println(""); 
            System.out.print(" "+i); 
            count++; 
            
        }
        }
    }

Welcome to CodeRanch, Jacob!

So, you want to repeat the program while the user finishes one repetition with a "y"?

[Jacob Smithenson]

I want it to complete the first run through, then prompt them with the y/n message, and then if yes it'll repeat the run through (and ask for all the info again).

So do you know of ways to make a certain piece of code run multiple times?
