将线程放到线程池中 要使用线程从里面拿即可
package com.mashibing.juc.c_000_threadbasic;import java.util.concurrent.*;public class T02_HowToCreateThread {static class MyCall implements Callable<String> {@Overridepublic String call() {System.out.println("Hello MyCall");return "success";}}//启动线程的5种方式public static void main(String[] args) throws Exception {ExecutorService service = Executors.newCachedThreadPool();// lambda表达式表示要执行的任务(方法)// 无返回值的执行(Runnable接口)service.execute(() -> {System.out.println("Hello ThreadPool");});// 带返回值的执行(Callable接口)Future<String> f = service.submit(new MyCall());String s = f.get();System.out.println(s);service.shutdown();}}
