executor java 异步方法之一

ExecutorService executor = Executors.newFixedThreadPool(2 * Runtime.getRuntime().availableProcessors());// 获取可执行线程数
        executor.execute(new Runnable() {
            
            @Override
            public void run() {
                Integer rs = 0;
                for (int i = 0; i < Integer.MAX_VALUE; i++) {
                    rs += i;
                }
                System.out.println(rs);
            }
        });
        System.out.println("请求已发出。。。。。");
