java 教程相应的代码 全是自己写的内附注释 很容易看明白的

package demo.chapter09.lock;

public class DeadLockDemo {

	public static void main(String[] args) {
		System.out.println("主线程开始");
		
		final StringBuffer sb = new StringBuffer("ABCD");
		
		Thread t = new Thread() {
			@Override
			public void run() {
				synchronized (sb) {
					sb.reverse();
				}
				System.out.println("子线程结束");
			}
		};
		t.start();
		System.out.println("子线程开始");
		
		synchronized (sb) {
			try {
				t.join();
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
			System.out.println(sb);
		}
		
		System.out.println("主线程结束");
	}
