这样的代码可用于在一个类内部通过另起线程来执行一个支线任务,一般这样的任务并不是该类的主要设计内容。
package com.zj.concurrency; public class startfrommethod { private thread t; private int number; private int count = 1; public startfrommethod(int number) { this.number = number; } public void runtask() { if (t == null) { t = new thread() { public void run() { while (true) { system.out.println("thread-" + number + " run " + count + " time(s)"); if (++count == 3) return; } } }; t.start(); } } public static void main(string[] args) { for (int i = 0; i < 5; i++) new startfrommethod(i).runtask(); } }
结果:
thread-0 run 1 time(s)
thread-0 run 2 time(s)
thread-1 run 1 time(s)
thread-1 run 2 time(s)
thread-2 run 1 time(s)
thread-2 run 2 time(s)
thread-3 run 1 time(s)
thread-3 run 2 time(s)
thread-4 run 1 time(s)
thread-4 run 2 time(s)
