Help linking a applet button to a text box Hello everyone. I have been working on this program for over a week. I really need some help getting this done. I was able to get the math.random to work but when I run my program as an applet I have a text box that I dont know how to link to my button. Can someone please show me how to do this?

publicclass JMathfun extends JApplet implements ActionListener {
int number1 = 1 + ( int )( Math.random() * 9 );
int number2 = 1 + ( int )( Math.random() * 9 );
Container con = getContentPane();
JLabel math = new JLabel(" What is : " + number1 + " TIMES " + number2);
JTextField userin = new JTextField(2);
JButton checkanswer = new JButton("Check Answer");
JLabel correct = new JLabel("Correct");
JLabel tryagain = new JLabel("Sorry, Please try again");
int rightanswer = number1 * number2;
publicvoid init() {
con.add(math);
con.add(userin);
con.add(checkanswer);
con.setLayout(new FlowLayout());
}
publicvoid actionPerformed(ActionEvent e)
{
con.add(tryagain);
con.add(correct);
}
}
Thanks for the help in advance.

You have the actionPerformed:
So add your 'linking' code there:
publicvoid actionPerformed(ActionEvent e)
{
con.add(tryagain);
con.add(correct);
}So add your 'linking' code there:
myTextField.setText("whatever you want"); //change text when button is clicked •

I might have it. I was able to get this from my book. Now all I need is to get home and try it out on my compiler .
publicvoid actionPerformed(ActionEvent e)
{
int answer = userin.getText();
if (answer == rightanswer) {
con.add(correct);
else
con.add(tryagain);
}
}
publicvoid actionPerformed(ActionEvent e)
{
int answer = userin.getText();
if (answer == rightanswer) {
con.add(correct);
else
con.add(tryagain);
}
}

you shouldn't add buttons inside actionPerformed
simply make the button (one is enough) beforehand (where you make your labels and the rest, and put in actionPerformed :
if (answer == ok) correct.setText("right");
else correct.setText("wrong");
or : correct.setText((answer == rightanswer ? "right" : "wrong"));

else correct.setText("wrong");
or : correct.setText((answer == rightanswer ? "right" : "wrong"));
maybe later
