Help linking a applet button to a text box

[krauz2]

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?

public class 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;

public void init() {

con.add(math);
con.add(userin);
con.add(checkanswer);

con.setLayout(new FlowLayout());

}

public void actionPerformed(ActionEvent e)
{

con.add(tryagain);
con.add(correct);

}

}

Thanks for the help in advance.

You have the actionPerformed:

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);
}

}

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"));
