Executors:工具类、线程池的工厂类,用于创建并返回不同类型的线程池
package oop.dxcgaoji; import java.util.concurrent.Executor; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; //测试线程池 public class TestPool { public static void main(String[] args) { //1.创建服务,创建线程池 //newFixedThreadPool 参数为:线程池大小 ExecutorService service = Executors.newFixedThreadPool(10); service.execute(new MyThread()); service.execute(new MyThread()); service.execute(new MyThread()); service.execute(new MyThread()); //2.关闭链接 service.shutdown(); } } class MyThread implements Runnable{ @Override public void run() { System.out.println(Thread.currentThread().getName()); } }
