一個死鎖的簡易好理解的Demo

package 死鎖demo;
public class DeadLock implements Runnable{
    boolean lockFormer;
    static Object o1 = new Object();
    static Object o2 = new Object();
    DeadLock(boolean loackFormer){
        this.lockFormer = loackFormer;
    }
    @Override
    public void run() {
        if(this.lockFormer) {
            synchronized(o1) {
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                synchronized(o2) {
                    System.out.println("1ok");
                }
            }
        }else {
            synchronized(o2) {
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                synchronized(o1) {
                    System.out.println("2ok");
                }
            }
        }
    }
}

package 死鎖demo;

public class TestThread {
    public static void main(String[] args){
        Thread t1 = new Thread(new DeadLock(true));
        Thread t2 = new Thread(new DeadLock(false));
        t1.start();
        t2.start();
    }
}

這裏運用synchronized和sleep方法產生了死鎖。因爲sleep方法和wait方法不同，sleep方法不會釋放內存鎖，所以因爲synchronized的存在導致產生了死鎖，無運行結果的產生。
這是我看網上一個大牛寫的，我覺得寫的很好簡單易懂，故此分享。
