the program in listing 2 illustrates this behavior. the program creates a thread, t1, whose only purpose in life is to create another thread, t2, whose destiny is to print a greeting, "pleased to meet you," for all eternity. if you run this code youll see that even though the main thread ends, t2 goes on forever, printing its tempting message. this behavior is due to the fact that t2 inherited its user... 下一页
