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) {
untDown = 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();
