is it possible to do this to methods?

[alacn]

String gg = "KeyEvent.VK_1";
robot.keyRelease(KeyEvent.VK_1);


could i some how put the gg variable in replace so its like robot.keyRelease(g);

Now i know the above code doesnt work, but is there a way like this to do it?

If you feel you're up to it, use reflection; read all about it in the API documentation for the Class and Field classes.

oh i see, good news. Im loving Javas flexibility to be honest.

Since keyRelease takes an int, not a String, you could code it this way:
int gg = KeyEvent.VK_1;
robot.keyRelease(gg);

But what to do if the OP only has a String value like "VK_1" or "VK_A"? The answer could be (gasp) reflection.

Sorry, I don't see how reflection converts a String to an int.
Sounds more like a javac function, but that is into byte code which could be returned as an int via a method call.

Field field= KeyEvent.class.getField("VK_1");
int value= field.getInt(null);

That's what reflection is all about ;-) I only use it as a last resort.

Thanks for that.

That's my new thing learned for today.

Something new on a Saturday? Oh dear, better forget all about it then because reflection (or even worse: the Introspector object) doesn't play the game by the rules. You can do anything you like with class objects or classes itself with that stuff. It makes you part of the virtual machine and breaks every protection or access right you'd normally have. Besides that, it's more expensive to use than ordinary object use; it's a poweful mechanism and extremely dangerous in the hands of newbies ...
