简单: 实现一个死锁代码

public class DeadLockDemo {

	static Printer p = new Printer();
	static Scaner s = new Scaner();

	public static void main(String[] args) {

		new Thread(new Runnable() {
			@Override
			public void run() {
				synchronized (s) {
					s.scan();
					try {
						Thread.sleep(1000);
					} catch (InterruptedException e) {
						e.printStackTrace();
					}
					synchronized (p) {
						p.print();
					}
				}
			}
		}).start();

		new Thread(new Runnable() {
			@Override
			public void run() {
				synchronized (p) {
					p.print();
					synchronized (s) {
						s.scan();
					}
				}
			}
		}).start();

	}

}

class Printer {

	public void print() {
		System.out.println("这个打印机在哼哧哼哧的打印~~~");
	}

}

class Scaner {

	public void scan() {
		System.out.println("这个扫描仪在呼哧呼哧的扫描~~~");
	}

}
