Java Button issue

I have this project and I have numerous steps to it. I am trying to figure out what I have to do to make my frame panel do what it is I am assigning it to do. I need the program to be able to tell when the user is clicking the round or oval button and than perform the proper mathmathical problem to give me the volume. I then want the volume to be placed on the same panel....Please HELP!!!!
if (rbutton)is selected than the problem will be double volume = ((length * width) * depth);else(rbutton1)than the problem will be double volume = ((length/2)^2) * depth);

I will copy just that part of the code and hope you guys can help me!!! the code works it shows everything...it just doesnt do the function!

JLabel l2 = new JLabel("Hot Tube");
JPanel p2 = new JPanel();
JLabel label7,label8,lable9;
final JTextField text7,text8,text9;
label7 = new JLabel();
label7.setText("Height:");
p2.add(label7);
text7 = new JTextField(20);
p2.add(text7);
JLabel space6 = new JLabel(" ");
p2.add(space6);
label8 = new JLabel();
label8.setText("Width:");
p2.add(label8);
text8 = new JTextField(20);
p2.add(text8);
JLabel space7 = new JLabel(" ");
p2.add(space7);
lable9 = new JLabel();
lable9.setText("Depth:");
p2.add(lable9);
text9 = new JTextField(20);
p2.add(text9);
JLabel space8 = new JLabel(" ");
p2.add(space8);
JRadioButton rbutton = new JRadioButton("Oval");
p2.add(rbutton);
JRadioButton rbutton1 = new JRadioButton ("Round");
p2.add(rbutton1);
JButton button2 = new JButton("Enter");
p2.add(button2);

tab.addTab( "Hot Tube", null, p2, " Hot Tube" );

Hi Friend,

You can use the following code:

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
class JButtonExample extends JFrame implements ActionListener {
JTextField t1,t2,t3;
JButtonExample (){
t1=new JTextField(20);
t2=new JTextField(20);
t3=new JTextField(20);
JLabel l1=new JLabel("Length: ");
JLabel l2=new JLabel("Width: ");
JLabel l3=new JLabel("Depth: ");
JButton b1=new JButton("Oval");
JButton b2=new JButton("Round");
JPanel p=new JPanel(new GridLayout(4,2));
p.add(l1);
p.add(t1);
p.add(l2);
p.add(t2);
p.add(l3);
p.add(t3);
p.add(b1);
p.add(b2);
b1.addActionListener(this);
b2.addActionListener(this);
add(p);
setVisible(true);
pack();
}
public void actionPerformed(ActionEvent e){
String choice = e.getActionCommand();
int length=Integer.parseInt(t1.getText());
int width=Integer.parseInt(t2.getText());
int depth=Integer.parseInt(t3.getText());

if(choice.equals("Oval")){
int volume = ((length * width) * depth);
System.out.println(volume);
}
else if(choice.equals("Round")){
int volume = (((length/2)^2) * depth);
System.out.println(volume);
}
}
public static void main(String[]args){
JButtonExample b=new JButtonExample();
}
}

It will be helpful for you.
Thanks
