輸出是什么笆呆？
============================
name_thread1
name_thread1
name_thread3
============================
new Thread(new A(), "name_thread2").run()和 new Thread(new A(), "name_thread3").start()不同的是 new Thread(new A(), "name_thread2").run()只是會(huì)在本線程內(nèi)部執(zhí)行亡笑，而 new Thread(new A(), "name_thread3").start()將會(huì)新建一個(gè)線程，然后在新建的線程中執(zhí)行run张咳，所以有以上結(jié)果。
