Code for One JButton? Help!

[Brook]

* I have an Input Box. We'll say someone types in the number 5.
* I have one Jbutton.
* I have one Text Field for the output.

What would a sample code look like? Behind JButton1 would be a calculation like "5.9 x Input Box value". So, is someone types in the number 5 in the Input Box and presses JButton1, the answer, which would be(in this example) 29.5, would display in the Text Field.

If I can see how it works for one button, I think I can get the others. THANKS.

I see that experts do not reply to your question. I am in the same boat. Thus new Javers help new Javers.
I do not know what you mean on Input Box. But for inputs into textField I would offer the following solution:

void cmdDo_actionPerformed(ActionEvent e) {
try{
int x = Integer.parseInt(txtInput.getText());
txtOutput.setText(String.valueOf(5.9 * x));
}
catch(NumberFormatException exp){
JOptionPane.showMessageDialog(null,exp,"Wrong Input",1);
}
}

Good luck.

you could also make a method that does the calculations for you, in case you have other arithmetic operations besides just 5.9

but in YOUR case:

yourButton.addActionListener(this);

public void actionPerformed(ActionEvent e)
{
if(e.getSource() == yourButton)
{
your calculation or method call;
}
