Do not use a textfield for output. Use a label instead. Have you gone through a simple event handling tutorial yet?

I was not giving you a link to a solution for your homework. I was pointing you to a tutorial. You should really be trying to do the homework yourself rather than trying to get someone to give you a solution.

Your reply really surprises me: the supplied example teaches you something
about converting X to Y. The example uses Fahrenheit and Celcius; your Xs
and Ys are centimeters and feet. It doesn't take a rocket scientist to convert
the example's constants and conversion formula to the constants and formulas
you need in your example.

kind regards,

ok sorry about that guys was in a bit of a rush last night, i sat down this morning and got the basics sorted here is my code:

private void cmdConvertActionPerformed(java.awt.event.ActionEve nt evt) {
int cm = (int)((Double.parseDouble(txtcm.getText()))
* 2.54);
lblOutput.setText(cm + " inches ");

However there is just 1 thing that i need help with now, i need the output not to come out as a interger but as a decimal

That's easy: make your 'cm' variable a double then and remove the (int) cast.
