将另外一个线程join到当前线程,则需要等到join进来的线程执行完才会继续执行当前线程。
package Thread.join; class Sleeper extends Thread { private int duration; public Sleeper(String name, int sleepTime) { super(name); duration = sleepTime; start(); } public void run() { try { sleep(duration); } catch (InterruptedException e) { System.out.println(getName() + " was interrupted." + "isInterrupted():" + isInterrupted()); return; } System.out.println(getName() + " has awakened"); } } class Joiner extends Thread { private Sleeper sleeper; public Joiner(String name, Sleeper sleeper) { super(name); this.sleeper = sleeper; start(); } public void run() { try { sleeper.join(); } catch (InterruptedException e) { System.out.println("Interrupted"); } System.out.println(getName() + " join completed"); } } public class Joining { public static void main(String[] args) { Sleeper sleepy01 = new Sleeper("Sleepy01", 1500), sleepy02 = new Sleeper( "Sleepy02", 1500); Joiner joiner01 = new Joiner("Joiner01", sleepy01), joiner02 = new Joiner("Joiner02", sleepy02); joiner01.interrupt(); } }
