以下实例演示了如何将线程挂起：
SleepingThread.java 文件
public class SleepingThread extends Thread {
private int countDown = 5;
private static int threadCount = 0;
public SleepingThread() {
super("" + ++threadCount);
start();
}
public String toString() {
return "#" + getName() + ": " + countDown;
}
public void run() {
while (true) {
System.out.println(this);
if (--countDown == 0)
return;
try {
sleep(100);
}
catch (InterruptedException e) {
throw new RuntimeException(e);
}
}
}
public static void main(String[] args)
throws InterruptedException {
for (int i = 0; i < 5; i++)
new SleepingThread().join();
System.out.println("线程已被挂起");
}
}
以上代码运行输出结果为：
#1: 5 #1: 4 #1: 3 #1: 2 #1: 1 …… #5: 3 #5: 2 #5: 1 线程已被挂起
