I tested it. You can check with this:

if (Thread.currentThread().getName().equals("main")) {
    // do something
}

Strangely, == doesn't work, but .equals() does. == probably compares the object, not the contents of the string.

really? tha sounds really faglie, i mean there's nothing to stop oracle from changing the name, between versions (hell they changed the jvm name, in jdk 6_21 and caused problems for eclipse)

Well, I suppose you could store the name of the thread in a global variable when the program first starts in main(), because you know for sure you're in the main thread then. Then you can compare to the stored value later.
