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.
