如果返回的值不是我关注的话,我应该如何在ExecutorService的 提交或执行之间进行选择？

如果我同时测试两者,除了返回值之外,我没有看到两者之间有任何差异.

ExecutorService threadExecutor = Executors.newSingleThreadExecutor();
threadExecutor.execute(new Task());

ExecutorService threadExecutor = Executors.newSingleThreadExecutor();
threadExecutor.submit(new Task());

我正在学习如何使用Java在Java中使用线程池ExecutorService，这是我正在处理的示例：

public class Example {
    static class WorkerThread implements Runnable {
        private String command;

        public WorkerThread(String s) {
            this.command = s;
        }

        @Override
        public void run() {
            System.out.println(Thread.currentThread().getName() + " Start. Command = " + command);
            processCommand();
            System.out.println(Thread.currentThread().getName() + " End.");
        }

        private void processCommand() {
            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }

        @Override
        public String toString() {
            return this.command;
        }
    }

    public static void main(String[] args) throws InterruptedException {
        ExecutorService executor = Executors.newFixedThreadPool(5); …
