java怎么实现延时

 
public static void main(String[] args) {
    Timer timer = new Timer();
    TimerTask timerTask = new MyTimerTask();
    timer.schedule(timerTask, 10000, 10000);    
}

public class MyTimerTask extends TimerTask{
    String userStatus = null;
    String key1 = null;
    String key2 = null;
    Jedis jedis = new Jedis("192.168.16.100",6379);
    
    @Override
    public void run() {
        // TODO Auto-generated method stub
        key1 = jedis.get("key1_13681033074");
        key2 = jedis.get("key2_13681033074");
        
        if(key1 != null && key2 == null){
            userStatus = "进入";
        }
 
        if(key1 != null && key2 != null){
            if(key1.equals(key2)){
                userStatus = "驻留";
            }else {
                userStatus = "进入";
            }
        }
 
        if(key1 == null && key2 != null){
            userStatus = "离开";
        }
        
        System.out.println(userStatus);
    }
}

try   
{   
Thread.currentThread().sleep(1000);//毫秒   
}   
catch(Exception e){}
