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.
