Java Program to accept the amount and display that amount in terms of Notes

The following Code is to get the possible number of notes within a particular amount.
Code:-

import java.util.*;
public class NoteNumber{
    Scanner scan=new Scanner(System.in);
    int amount,amt, r1, r2, r5, r10, r20, r50, r100, r500, r1000;
    public void input(){
        try{
            System.out.println("Enter the Total Amount: ");
            amount=scan.nextInt();
        }
        catch(NumberFormatException e){
            System.out.println("Error Code: "+e);
            System.exit(0);
        }
    }

    public void compute(){
        r1000=r500=r100=r50=r20=r10=r5=r2=r1=0;
        amt=amount;
        r1000=amount/1000;
        amount%=1000;
        r500=amount/500;
        amount%=500;
        r100=amount/100;
        amount%=100;
        r50=amount/50;
        amount%=50;
        r20=amount/20;
        amount%=20;
        r10=amount/10;
        amount%=10;
        r5=amount/5;
        amount%=5;
        r2=amount/2;
        amount%=2;
        r1=amount/1;
    }

    public void notes(){
        System.out.println("Total Amount: "+amt);
        System.out.println("Notes of 1000: "+r1000);
        System.out.println("Notes of 500: "+r500);
        System.out.println("Notes of 100: "+r100);
        System.out.println("Notes of 50: "+r50);
        System.out.println("Notes of 20: "+r20);
        System.out.println("Notes of 10: "+r10);
        System.out.println("Notes of 5: "+r5);
        System.out.println("Notes of 2: "+r2);
        System.out.println("Notes of 1: "+r1);
    }

    public static void main(String[] args){
        NoteNumber note=new NoteNumber();
        note.input();
        note.compute();
        note.notes();
    }
}

Output:-
Enter the Total Amount:
29187
Total Amount: 29187
Notes of 1000: 29
Notes of 500: 0
Notes of 100: 1
Notes of 50: 1
Notes of 20: 1
Notes of 10: 1
Notes of 5: 1
Notes of 2: 1
Notes of 1: 0
