这篇文章主要介绍了java Lock接口详解及实例代码的相关资料,需要的朋友可以参考下

java Lock接口

java.util.concurrent.locks

接口Lock

public interface Loce

Loce实现提供了比使用synchronized方法和语句可获得的更广泛的锁定操作

									public class IntegerDemo {

									  public static void main(String[] args) {

									    // 创建3个线程对象

									class SellTicket implements Runnable {

									  private int ticket = 100;

									  private Lock lock = new ReentrantLock();

									  public void run() {
