I am building a GUI for a bank as my project. I have the frame and panel built, but am having trouble with the listeners. I am trying to get it so that when you enter the amount you want to withdraw or deposit and click the Balance button, it adds or subtracts the value you entered from your balance.

BankFrame.java

//Date //Author:

import javax.swing.JFrame;

public class BankFrame {

public static void main(String[] args) { //Object with frame title JFrame frame = new JFrame("Meal Selector"); //Close button frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Bankpanel panel = new Bankpanel(); frame.getContentPane().add(panel); //size of frame frame.setSize(500, 1000); //make frame visible frame.setVisible(true);

}

}

Bankpanel.java

import java.util.*; import java.text.NumberFormat;

public class BankPanel extends JPanel {

//1. declare instance variables in panel class level // create components private JLabel balanceL, optionL, withdrawL, depositL, remainingL; private JTextField withdraw, deposit, remaining; private JButton balance, Clear; private JRadioButton withdrawR, depositR; //panel constructor BankPanel(){ //List of components //Labels balanceL = new JLabel ("Bank account balance: $5826"); optionL = new JLabel ("Select your option: "); withdrawL = new JLabel ("How much would you like to withdraw?: "); depositL = new JLabel ("How much would you like to deposit?: "); remainingL = new JLabel ("Remaining balance: "); //Text fields withdraw = new JTextField(10); deposit = new JTextField(10); remaining = new JTextField(10); //Buttons balance = new JButton ("Balance"); Clear = new JButton ("Clear"); //Radio buttons (must be grouped together) withdrawR = new JRadioButton("Withdraw"); depositR = new JRadioButton("Deposit"); ButtonGroup transGroup = new ButtonGroup(); transGroup.add(withdrawR); transGroup.add(depositR); //Listeners balance.addActionListener(new remainingListener()); Clear.addActionListener(new ClearListener()); //Adding components to panel add (balanceL); add (optionL); add (withdraw); add (deposit); add (withdrawL); add (withdraw); add (depositL); add (deposit); add (remainingL); add (remaining); add (balance); add (Clear); //Size and background for panel setPreferredSize(new Dimension(500, 1000)); setBackground(Color.blue); } private class remainingListener implements ActionListener { public void actionPerformed (ActionEvent event){ double w, d, r; String withdrawText = withdraw.getText(); String depositText = deposit.getText(); w = Double.parseDouble(withdrawText); d = Double.parseDouble(depositText); } } }
