Thank you for acknowledging my problem.

I need java source code on the problem I've post, I am actually using a JFrame component for my cashdispenser.java and I don't know how build a source code on my problem.

The flow is just like this

Enter amount to widthdraw:_______________
Initial Balance:__________


CashDispenserButton


On this button it should show on how many were taken from the atm:

For instance an atm have 1000 pcs. of 1000 pesos and 500 pcs of 500 pesos and 100pcs. of 100 pesos. So if I put an amount in Enter amount to Widthraw and click the CashDispenser Button that should show or prompt a message dialouge box on how many were taken from the amount of money stored there..

So example if I widthraw an amount of 6500 pesos.. CashDispenser should show how many were taken from the 1000pcs of 1000pesos and 500pcs. of 500 pesos and 100pcs. of 100 pesos..

I'm sorry I am not that good in english hope I communicated it well to you..

one more thing the maximum amount to be widthrawn is 10,000 pesos only

Hi Friend,

Try the following code:

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

class CashDispenser extends JFrame{
JLabel l1,l2;
JTextField t1,t2;
JButton b;
JPanel p;

CashDispenser(){
l1=new JLabel("Enter amount to withdraw:");
l2=new JLabel("Initial Balance: ");
b=new JButton("");
t1=new JTextField(20);
t2=new JTextField(20);
p=new JPanel(new GridLayout(3,2));
b.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
int[] a = {1000,500,100};
String[] str = {"1000 peso","500 peso","100 peso"};
String value=t1.getText();
int amount=Integer.parseInt(value);
if(amount>10000){
JOptionPane.showMessageDialog(null,"You cannot withdraw more than 10,000 pesos");
}
else{
int[] pesos = {0,0,0};
for(int i=0;i<a.length;i++){
if(a[i]<amount || a[i]==amount){
pesos[i]=amount/a[i];
amount=amount%a[i];
}
}
String st="";
for(int i=0;i<pesos.length;i++){
if(pesos[i]!=0){
st+="No of " + str[i] +"="+ pesos[i]+"\n";

}
}
JOptionPane.showMessageDialog(null,st);
}
}
});
p.add(l1);
p.add(t1);
p.add(l2);
p.add(t2);
p.add(b);
add(p);
setVisible(true);
pack();
}
public static void main(String[]args){
CashDispenser c=new CashDispenser();

}
}

Hope that it will be helpful for you.
Thanks
