- 程序员想要创建一个名为MyThread的类以便在main方法中用Thread实例化。对于下面三行:MyThread必须继承Thread。MyThread必须实现Thread。MyThread必须覆盖publicvoidrun()。有几行是正确的() A.0 B.1 C.2 D.3
- A046阅读下面程序publicclassTest2___________{publicstaticvoidmain(String[]args){Threadt=newTest2(); t.start();}publicvoidrun(){System.out.println(“Howareyou.”);}}在程序下划线处填入正确选项是（）（1.0分）
