If you have any problem with the code feel free to comment.

Program

import javax.swing.JFrame;
import javax.swing.JOptionPane;

class ATM {
   //instance variables
   private int balance, withdraw, deposit;
  
   //setters
   public void setBalance(int balance) {
       this.balance = balance;
   }

   public void setWithdraw(int withdraw) {
       this.withdraw = withdraw;
   }

   public void setDeposit(int deposit) {
       this.deposit = deposit;
   }
  
   public void performDeposit() {
       if(deposit>0) {//if value is less than zero balance remain unchanged
           balance += deposit;          
       }
   }
  
   public void performWithdraw() {
       if(withdraw<balance) {//if withdraw is greater than balance, balance remain unchanged
           balance -= withdraw;          
       }
   }
   //for showing reciept
   public void showReciept() {
       System.out.println("**********Reciept**********");
       System.out.println("Initial Balance: $"+balance);
       System.out.println("Withdraw Amount: $"+withdraw);
       performWithdraw();
       System.out.println("Balance after withdraw: $"+balance);
       System.out.println("Deposit Amount: $"+deposit);
       performDeposit();
       System.out.println("Balance after deposit: $"+balance);
   }
  
}

public class Test {
   public static void main(String[] args) {
       JFrame frame = new JFrame();
       ATM obj = new ATM();
       //getting user input using JOptionPane
       String balance = JOptionPane.showInputDialog(frame,"Enter Balance");
       String withdraw = JOptionPane.showInputDialog(frame,"Enter Withdraw");
       String deposit = JOptionPane.showInputDialog(frame,"Enter Deposit");
       //setting user input
       obj.setBalance(Integer.parseInt(balance));
       obj.setWithdraw(Integer.parseInt(withdraw));
       obj.setDeposit(Integer.parseInt(deposit));
       obj.showReciept();//showing reciept
       System.exit(0);
   }
}

Output
