线程池的使用示例说明

线程池使用示例:
  1.定义线程类
  2.定义线程池
  3.将线程类实例 放入线程池中，启动线程池

创建线程类
 
public class runnabledemo implements Runnable {
    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName()+" 正在执行...");
    }
}

 
创建测试类
 
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

 
public class demo01 {
    public static void main(String[] args) {
        //1.创建线程池
        ExecutorService executorService = Executors.newFixedThreadPool(2);
        //2.调用线程池中的线程执行指定的线程对象
        executorService.submit(new runnabledemo());
        executorService.submit(new runnabledemo());
        executorService.submit(new runnabledemo());
        //3.销毁线程池(不建议执行)
        executorService.shutdown();
    }
}
