一、实现一个最简单的线程
public class LiftOff implements Runnable{ protected int countDown = 10; private static int taskCount = 0; private final int id = taskCount++; public LiftOff() {} public LiftOff(int countDown) { this.countDown = countDown; } public String status() { return "#" + id + "(" + (countDown > 0 ? countDown : "LiftOff!") + ")"; } /* (non-Javadoc) * @see java.lang.Runnable#run() */ @Override public void run() { while (countDown-- > 0) { System.out.println(status()); Thread.yield(); // 告诉CPU可以进行线程切换。 } } } |
然后，你以后再调用以下代码就可以开启一个新线程。下面代码调用t.start()函数之后就会执行 LiftOff类的run函数。
Thread t = new Thread(new LiftOff()); t.start(); |
