Hi,
I ran the following code
I know that call to currentThread() returns a reference to the currently executing thread ,but from the output I do not understand the other components that are returned.
Apart of the thread name (Thread-0 or main) what is the meaning of this "5,main"



The following is the output:

Current Thread Thread[main,5,main]
User Thread Thread[Thread-0,5,main] 1
User Thread Thread[Thread-0,5,main] 2
User Thread Thread[Thread-0,5,main] 3
User Thread Thread[Thread-0,5,main] 4
User Thread Thread[Thread-0,5,main] 5
User Thread Thread[Thread-0,5,main] 6
User Thread Thread[Thread-0,5,main] 7
User Thread Thread[Thread-0,5,main] 8
User Thread Thread[Thread-0,5,main] 9

5 is the default Thread priority

the last information, main, is the Thread Group which your current thread belongs to.

You can refer to java6 API to see how interact with those Thread attributes.
You can for example change thread name and priority with setName and setPriority methods

About Thread groups you can read the ThreadGroup class detailed description
