代码示例 1.创建一个可重用固定线程数的线程池 Executors.newFixedThreadPool(n) //1.创建一个可重用固定线程数的线程池 Executors.newFixedThreadPool...(n) ExecutorService pool = Executors.newFixedThreadPool(5); 2.使用 Callable 接口创建一个匿名线程，并且使用线程池的线程启动 @Test...public void test01() throws ExecutionException, InterruptedException { //1.创建一个可重用固定线程数的线程池 Executors.newFixedThreadPool...(n) ExecutorService pool = Executors.newFixedThreadPool(5); //2.使用 Callable 接口创建一个匿名线程，并且使用线程池的线程启动...(n) ExecutorService pool = Executors.newFixedThreadPool(5); //2.使用线程池跑10个线程 //2.1 创建一个集合接收返回的结果
Executors.newFixedThreadPool(int nThreads) ,创建一个可重用固定线程数的线程池。这个线程池里最多包含nThread个线程。...e) { e.printStackTrace(); } }; ExecutorService pool = Executors.newFixedThreadPool...e) { e.printStackTrace(); } }; ExecutorService pool = Executors.newFixedThreadPool...看下面的例子： public void wrongSubmit() throws InterruptedException { ExecutorService pool = Executors.newFixedThreadPool...public void useFuture() throws InterruptedException { ExecutorService pool = Executors.newFixedThreadPool
参数为个数，返回值为线程池对象； 步骤： 1、创建线程池对象； 2、创建Runnable接口子类对象； 3、提交Runnable接口子类对象； 测试类 ExecutorService es = Executors.newFixedThreadPool...System.out.println(Thread.currentThread().getName()+"的方法"); } } 执行结果 ExecutorService es = Executors.newFixedThreadPool...submit提交线程任务； Future submit(Callable c) Future的get()方法获取线程任务的返回值 测试类 ExecutorService es = Executors.newFixedThreadPool
创建线程池 ExecutorService executorService = Executors.newFixedThreadPool(3);...创建线程池 ExecutorService executorService = Executors.newFixedThreadPool(3);...创建线程池 ExecutorService executorService = Executors.newFixedThreadPool(3);...创建线程池 ExecutorService executorService = Executors.newFixedThreadPool(3);...创建线程池 ExecutorService executorService = Executors.newFixedThreadPool(3);
然而当程序在多线程并发执行调用这个方法的时候 //就会产生线程不安全的问题 private static final ExecutorService executorService = Executors.newFixedThreadPool...LocalDateTime.parse(date, dateTimeFormatter); } private static final ExecutorService executorService = Executors.newFixedThreadPool...LocalDateTime.parse(date, dateTimeFormatter); } private static final ExecutorService executorService = Executors.newFixedThreadPool
添加具体的代码，如下所示： ExecutorService service = Executors.newFixedThreadPool(3); SynchronizedMethod summation...; service.awaitTermination(1000, TimeUnit.MILLISECONDS); assertEquals(1000, summation.getSum()); 1）Executors.newFixedThreadPool...修改一下测试用例： @Test void synchronizedCalculate() throws InterruptedException { ExecutorService service = Executors.newFixedThreadPool...Test void synchronizedCalculate() throws InterruptedException { ExecutorService service = Executors.newFixedThreadPool...新建一个测试用例： @Test void synchronisedThis() throws InterruptedException { ExecutorService service = Executors.newFixedThreadPool
代码片段： ExecutorService executorService = Executors.newFixedThreadPool(1); Future futureTask =...ExecutorService executorService = Executors.newFixedThreadPool(1); Future futureTask = executorService.submit...ExecutorService executorService = Executors.newFixedThreadPool(1); Future futureTask = executorService.submit
创建线程池 ExecutorService executorService = Executors.newFixedThreadPool(3); ListExecutors.newFixedThreadPool(3); List...创建线程池 ExecutorService executorService = Executors.newFixedThreadPool(3); List...创建线程池 ExecutorService executorService = Executors.newFixedThreadPool(3); List...创建线程池 ExecutorService executorService = Executors.newFixedThreadPool(2); // 2.
) { ExecutorService threadPool = Executors.newSingleThreadExecutor();//创建单个线程的线程池 //Executors.newFixedThreadPool...PS： 因为线程池只有一个线程，所以线程名字都一样； 2、Executors.newFixedThreadPool(int num) 概述： 创建固定线程数量的线程池； 代码实现： package com.zibo.pool...threadPool = Executors.newSingleThreadExecutor();//创建单个线程的线程池 ExecutorService threadPool = Executors.newFixedThreadPool...threadPool = Executors.newSingleThreadExecutor();//创建单个线程的线程池 //ExecutorService threadPool = Executors.newFixedThreadPool
CompletableFuture future1 = CompletableFuture.runAsync(() -> System.out.println("runAsync"), Executors.newFixedThreadPool...(4)); CompletableFuture future2 = CompletableFuture.supplyAsync(() -> "supplyAsync", Executors.newFixedThreadPool
方法一：自己维护返回结果 // 创建一个线程池 ExecutorService executorService = Executors.newFixedThreadPool(10); // 存储执行结果的...// 创建一个线程池 ExecutorService executorService = Executors.newFixedThreadPool(10); // 创建存储任务的容器 ListExecutors.newFixedThreadPool(10); final BlockingQueue> queue
class Test { public static void main(String[] args) { ExecutorService executorService = Executors.newFixedThreadPool...上菜宫保鸡丁2 上菜宫保鸡丁1 如果修改核心线程为3，即修改代码中 ExecutorService executorService = Executors.newFixedThreadPool(...Test { public static void main(String[] args) { ExecutorService orderExecutorService = Executors.newFixedThreadPool...(1); ExecutorService cookExecutorService = Executors.newFixedThreadPool(1); orderExecutorService.submit
Runnable实例 关闭线程池 // public static ExecutorService newFixedThreadPool(int nThreads) ExecutorService pool = Executors.newFixedThreadPool...pool.submit(new MyRunnable()); //结束线程池 pool.shutdown(); 多线程程序实现的方式3 // 创建线程池对象 ExecutorService pool = Executors.newFixedThreadPool
TestThread4 testThread4 = new TestThread4(); // 创建执行服务 ExecutorService executorService = Executors.newFixedThreadPool...TestThread8 { public static void main(String[] args) { // 创建线程池 ExecutorService service = Executors.newFixedThreadPool
givenMultiThread_whenNonSyncMethod() throws InterruptedException { ExecutorService service = Executors.newFixedThreadPool...} 看下调用结果： @Test public void givenMultiThread_whenMethodSync() { ExecutorService service = Executors.newFixedThreadPool...void givenMultiThread_whenBlockSync() throws InterruptedException { ExecutorService service = Executors.newFixedThreadPool
// 例子public static void main(String[] args) { // 快速创建线程池 ExecutorService executor = Executors.newFixedThreadPool...// 例子public static void main(String[] args) {// 快速创建线程池ExecutorService executor = Executors.newFixedThreadPool...// 例子public static void main(String[] args) { // 快速创建线程池 ExecutorService executor = Executors.newFixedThreadPool...// 例子public static void main(String[] args) {// 快速创建线程池ExecutorService executor = Executors.newFixedThreadPool...public static void main(String[] args) { // 快速创建线程池 ExecutorService executor = Executors.newFixedThreadPool
触发报警的代码大概如下： boolean start=true; public void doSomeThing(){ ExecutorService executorService = Executors.newFixedThreadPool...; ExecutorService executorService; Thread thread ; public void doSomeThing(){ executorService = Executors.newFixedThreadPool
{ public static void main(String[] args) { // 创建线程池对象 ExecutorService service = Executors.newFixedThreadPool...static void main(String[] args) throws Exception { // 创建线程池对象 ExecutorService service = Executors.newFixedThreadPool...main(String[] args) throws ExecutionException, InterruptedException { ExecutorService pool = Executors.newFixedThreadPool
ExecutorService executorService0 = Executors.newFixedThreadPool(10); ExecutorService executorService1...带着这个问题，我们来研究一下，只要看过线程池源码的同学都知道，不管是 Executors.newFixedThreadPool() ，Executors.newSingleThreadExecutor(...TimeUnit.SECONDS, new SynchronousQueue()); } 固定线程Executors.newFixedThreadPool
