how to differentiate between two threads

Question

Hello everyone,

I have the following code in my program:

Thread getUsersist, getChatUsers;

getUsersList = new Thread(this, "getOnlineUsers");
getUsersList.start();
getChatUsers = new Thread(this, "getChatUsers");
getChatUsers.start();

In run(), I wish to know which thread is using run(). If its "getOnlineUsers" i will do something, If it is "getChatUsers" I will do something else. So how do I know which thread is using run()?

Answer 1

In run(), you can do:

Thread.currentThread().getName()

to get either "getOnlineUsers" or "getChatUsers" and take a different code path accordingly. That said, it seems like a rather fragile design to me and I'd imagine you'd be far better off with separate classes for each thread.

HTH,

Answer 2

if (getName().equals("getOnlineUsers")) {
    doOneThing();
else if (getName().equals("getChatUsers")) {
    doAnotherThing();
} else {
    throw Up();
}
