編程開發之--java多線程學習總結（5）

4、對繼承自Runnable的線程進行鎖機制的使用

package com.lfy.ThreadsSynchronize;import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;public class TicketSellSolution4 implements Runnable {private static int num = 50;//創建一個鎖對象Lock l = new ReentrantLock();@Overridepublic void run() {for(int i = 0 ; i < 50 ;i ++){//獲取鎖
            l.lock();try {if(num > 0){Thread.sleep(10);System.out.println(Thread.currentThread().getName()+"賣出一張票，剩余"+(--num)+"張");}} catch (Exception e) {e.printStackTrace();}finally{//釋放鎖
                l.unlock();}}}}
