问题分析

通过调用interrupt()方法，线程在sleep/wait/join时，会抛出InterruptedException，可以在适当地方配合isInterrupted()方法检查中断状态，并对异常进行捕获并处理，这样线程不用继续等待，线程控制权直接会转给catch住异常块的代码。

解决方案

线程在sleep/wait/join时如果对线程调用interrupt方法，会抛出InterruptedException，对该类异常进行捕获，可以获得线程控制权，继续执行任务。

代码示例

public class PlayerMatcher {
    private PlayerSource players;
    public PlayerMatcher(PlayerSource players) { 
        this.players = players; 
    }
    public void matchPlayers() throws InterruptedException { 
        try {
             Player playerOne, playerTwo;
             while (true) {
                 playerOne = playerTwo = null;
                 // Wait for two players to arrive and start a new game
                 playerOne = players.waitForPlayer(); // could throw IE
                 playerTwo = players.waitForPlayer(); // could throw IE
                 startNewGame(playerOne, playerTwo);
             }
         }
         catch (InterruptedException e) {  
             // If we got one player and were interrupted, put that player back
             if (playerOne != null)
                 players.addFirst(playerOne);
             // Then propagate the exception
             throw e;
         }
    }
}
