Help simplify conversion code for fahrenhiet and Celcius

[dfluker]

Does anyone know a way that i can simplify this code?

Here is my code. Basically it allows me to enter an integer and I can prompt the user to press one of two buttons which then converts the integer into Fahrenhiet or Celcius.

Here is my code:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
 
public class FtoCConversionTest{
    public static void main(String[] args){
        EventQueue.invokeLater(new Runnable(){
            public void run(){
                ConvertorFrame frame = new ConvertorFrame();
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setVisible(true);
            }
        });
    }
}
 
class ConvertorFrame extends JFrame{
 
    public ConvertorFrame(){
        setTitle("Fahrenheit to Celsius Calculator");
        ConvertorPanel panel = new ConvertorPanel();
        add(panel);
        pack();
    }
}
 
class ConvertorPanel extends JPanel{
 
    public ConvertorPanel(){
 
        setLayout(new BorderLayout());
        //add the panel
        panel = new JPanel();
 
        //add JTextField and position it
        textField = new JTextField();
        JPanel northPanel = new JPanel();
        northPanel.setLayout(new GridLayout(2,1));
        //add the text field label and position it
        northPanel.add(new JLabel("Type the number to convert below: ", SwingConstants.LEFT));
        northPanel.add(textField);
        add(northPanel, BorderLayout.NORTH);
 
        //set the panel and position it
        panel.setLayout(new GridLayout(1,2));
        //add buttons and position them
        cButton = new JButton("Convert to Celsius");
        panel.add(cButton);
        fButton = new JButton("Convert to Fahrenheit");
        panel.add(fButton);
        add(panel, BorderLayout.SOUTH);
 
        Converter  converter = new Converter();
        cButton.addActionListener(converter);
        fButton.addActionListener(converter);
 
    }
    private class Converter implements ActionListener{
 
        public void actionPerformed (ActionEvent event){
 
            if (event.getSource() == cButton){
                int c = (int)(((Double.parseDouble(textField.getText()))- 32) * 0.56);
                textField.setText(c + " °C");
                textField.requestFocus();
                textField.selectAll();
            }
            else if(event.getSource() == fButton){
                int f = (int)(((Double.parseDouble(textField.getText()))* 1.8) + 32);
                textField.setText(f + " ºF");
                textField.requestFocus();
                textField.selectAll();
            }
        }
    }
    private JButton cButton, fButton;
    private JTextField textField;
    private JPanel panel;
}

thanks in advance

It looks pretty simplified to me.
