Hello

I'm a real noob with java. I worked for 4 years with php but now I have
to use java.
I'm looking for a clean way to get an action behind a button/menuitem. I
already found the class actionListener. but the method actionpreformed
is not very clean if you want to give 20 buttons an action. The way I
know is 20 times else if. There must be an better method.

I will try to use my GUI like an interface. It does'nt have to include
much code in my opinion. I think it have to be only some field and
button delcarations.

thx for your help

There are 2 ways (that I know of and can remember from class) for
designing the way your application handles the action events. You can
have your JFrame or JPanel (some central "authority") manage all the
events which would cause you to need a bunch of "else if" statements or
you can have each button be its own action listener which removes the
need for a large "if" structure but makes the individual button code a
little more messy, IMO.
