"Messaging" between classes

[Sen7inel]

Hi,

let's say I have two classes: mainApp and myThread (extends Thread).

mainApp creates a myThread object, which does this and that, and once it does something specific, it should tell mainApp that it I've done it. Is there any neater way to do this than tell the myThread object (for example in constructor parameters: myThread th = new myThread(this) which object called it?

A thread can get the ThreadGroup it belongs to:

Threadgroup myGroup = getThreadGroup();

then it can get the parent Threadgroup:

Threadgroup parentGroup = myGroup.getParent();

You can then use parentGroup.enumerate to go through all the threads looking for the one to send the message to.

Hope this helps.
