接上一篇部落格，使用Lock實現死鎖

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class DeadlockLock {
    private static Lock lock1 = new ReentrantLock();
    private static Lock lock2 = new ReentrantLock();

    public static void main(String[] args) {
            // TODO Auto-generated method stub
 

        Thread thread1 = new Thread(new Runnable() {
            @Override
            public void run() {
                lock1.lock();//獲取鎖1
                System.out.println(Thread.currentThread().getName()+"獲取了lock1");
                try {
                    Thread.sleep(500);
                }catch
 
 (InterruptedException ex){
                    ex.printStackTrace();
                }
                lock2.lock();
                System.out.println(Thread.currentThread().getName()+"獲取了lock2");
                lock2.unlock();
                lock1.unlock();
            }
        },"thread1");
        Thread thread2 = new
 
 Thread(new Runnable() {
            @Override
            public void run() {
                lock2.lock();//獲取鎖2
                System.out.println(Thread.currentThread().getName()+"獲取了lock2");
                try {
                    Thread.sleep(500);
                }catch (InterruptedException ex){
                    ex.printStackTrace();
                }
                lock1.lock();
                System.out.println(Thread.currentThread().getName()+"獲取了lock1");
                lock1.unlock();
                lock2.unlock();
            }
        },"thread2");
        thread1.start();
        thread2.start();
    }
}
