死锁：在两个线程对同步对象具有依赖，就会出现死锁。以下是简单的示例：

package org.test.code;

public class DeadLock {

    public static void main(String[] args) {
        final Object resource1 = "resource1";
        final Object resource2 = "resource2";
        Thread t1 = new Thread() {
            public void run() {
                synchronized (resource1) {
                    System.out.println(Thread.currentThread().getName() + ":"
                            + " locked resource 1");
                    synchronized (resource2) {
                        System.out.println(Thread.currentThread().getName()
                                + ":" + " locked resource 2");
                    }

                }
            }
        };

        Thread t2 = new Thread() {
            public void run() {
                synchronized (resource2) {
                    System.out.println(Thread.currentThread().getName() + ":"
                            + " locked resource 2");
                    synchronized (resource1) {
                        System.out.println(Thread.currentThread().getName()
                                + ":" + " locked resource 1");
                    }
                }
            }
        };
        t1.start();
        t2.start();
    }
}
