Putting code in while or for statement

[broception]

I been working on a program for class, and I finished it but I was wondering if I could put the code into a while statement to make it easier to read. If it's possible, can someone show me how?

import java.util.Scanner;
 
public class Problem3 {
 
    //*** User input amount then print out amount in fewest number of bills
 
    public static void main(String[] args) {
        Scanner keyboard=new Scanner(System.in);
        int amount;
        int twenty;
        int ten;
        int five;
        int one;
 
        System.out.print("Enter amount: ");
        amount=keyboard.nextInt();
 
        twenty = amount/20;
        amount = amount%20;
        System.out.println("$20 dollar bills: " + twenty);
 
        ten = amount/10;
        amount = amount%10;
        System.out.println("$10 dollar bills: " + ten);
 
        five = amount/5;
        amount = amount%5;
        System.out.println("$5 dollar bills: " + five);
 
        one = amount/1;
        amount = amount%1;
        System.out.println("$1 dollar bills: " + one);
 
 
    }
 
}

You only use while or for when there is a loop. You don't have a loop in the code. You can improve the readability however by declaring variables as close to where they are used as possible.
