Closed Pahelp about loops java

[djdoolky76]

Baka hindi mo nailagay si Scanner, nagbase lang kasi ako sa sinend mo eh
Pero eto boss sure nato triny ko na para sayo.

import java.util.*;
public class Main
{
    public static void main(String[] args) {
        Scanner input = new Scanner (System.in);
       
        char rep;
        char repnum;
        int loop;
       
        do{
           
        int  jeff = 0;
        int counter = 0;
        float ave;
        System.out.println("How many numbers that you want to add?");
        loop = input.nextInt();
            do{
                for (int x = 0;loop > x;x++){
                System.out.println("Input any number you want to add");
                int jeff2 = input.nextInt();
                jeff += jeff2;
                counter += 1;
                }
            System.out.println("Do you want to add another number?\nY - Yes\nN - No\n");
            repnum = input.next().charAt(0);
            }while(repnum == 'Y' || repnum == 'y');
       
        ave = jeff / counter;
        System.out.println("Sum is : " + jeff);
        System.out.println("Average is : " + ave);

        System.out.println("\n\nDo you want to get another average?\nY - Yes\nN - No\n");
        rep = input.next().charAt(0);
        }while(rep == 'Y' || rep == 'y');
    }
}

okay na paps.. na lagyan kona

Invalid input! Please try again.
Enter an integer value ('0' to exit): b
Invalid input! Please try again.

Sum: 6
Average: 2.000000

RikkuRikku Also I wanna point out two things on your question:

1. Fix the code formatting. You are asking people to look at your code snippet. You might as well do the formatting correctly.
2. Also use Java as the language and not JavaScript. They are not the same language.

Most of the issues I see in code are caused by unreadable and untidy code. If it's hard to read in the eyes of a senior developer then probably that code is bad.
