题目内容
public class Holt extends Thread{ private String sThreadName; public static void main(String argv[]){ Holt h = new Holt(); h.go(); } Holt(){} Holt(String s){ sThreadName = s; } public String getThreadName(){ return sThreadName; } public void go(){ Holt first = new Holt("first"); first.start(); Holt second = new Holt("second"); second.start(); } public void start(){ for(int i = 0; i < 2; i ++){ System.out.println(getThreadName() +i); try{ Thread.sleep(100); } catch(InterruptedException e){ System.out.println(e.getMessage()); } } } } 当编译运行上面的Java代码时,将会出现()。
