Problem with decimal numbers..

Question

hi i posted the other day with a problem I had. I thought it was all sorted but I have just realised that there is another problem.
I have the following code for an applet:
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
public class TextFieldExample extends Applet implements ActionListener {
TextField textInput;
String text = "";
public void init() {
textInput = new TextField (20);
add(textInput);
textInput.addActionListener(this);
public void actionPerformed(ActionEvent e) {
text = textInput.getText();
repaint();
public void paint(Graphics g) {
     int x = Integer.parseInt(text);
     double y = Math.abs(x);
g.drawString("You wrote " + text,20,500);
     g.drawString("The absolute value is: " + y,20,100);
I am trying to do the applet so when you type in an angle, it tell you the sine, cosine etc. I can get it to work with whole numbers like 1,10,300, but it won't work when i try to use decimal numbers. Can anyone help?
Thnk you in advance!

Hi,
you are using Integer.parseInt() to convert the input, so it will only work if the text is an integer. Use Double.parseDouble() instead.
