下列代码编译或执行结果的描述中,正确的是: class Test{ public static void main(String args[]){ TestThread pm1 = new TestThread("One"); pm1.start(); TestThread pm2 = new TestThread("Two"); pm2.start(); } } class TestThread extends Thread{ private String sTname=""; TestThread(String s){ sTname = s; } public void run(){ for(int i=0;i<2;i++){ try { sleep(1000); } catch (InterruptedException e) {} System.out.println(sTname+" "); } } }
A.不能通过编译,TestThread 类中不能定义变量和构造方法 B.输出One One Two Two C.输出Two One One Two D.选项B 或C 都有可能出现正确答案D
