What happens if we call newThread.join(), before newThread.start(), let's say, in main method (thread)? I didn't see any effects...

Nothing. The method just returns... which you have seen.

Following is the implementation of Thread.join(long millis). Calling newThread.join() leads to join(0) being called which in turn,as Henry said,causes the method to return,because isAlive() for a thread that has not been started would return false.

 
It is sorta covered in the JavaRanch Style Guide.
