java - 将方法提交到 ExecutorService Java

Question

所以我这里有这段代码，它将我的“NamePrinter”可运行类添加为 ExecutorService 任务。一切正常，但我想摆脱那个额外的类(class)。所以我问有没有办法向 ExexutorService 提交方法？

这是我目前拥有的代码:

public void start(){
        Collection<Future<?>> futures = new LinkedList<>();
        final ExecutorService es = Executors.newFixedThreadPool(poolSize);

        for (int i = 0; i < 10; i++) {
        futures.add(es.submit(new NamePrinter(name)));
        }

        es.shutdown();
}

但我希望它是这样的:

public void start(){
            Collection<Future<?>> futures = new LinkedList<>();
            final ExecutorService es = Executors.newFixedThreadPool(poolSize);

            for (int i = 0; i < 10; i++) {
            futures.add(es.submit(namePrint(i+"name"))); // This code doesn't work, I just made it so you could understand what I mean.
            }

            es.shutdown();
    }

public void namePrint(String name){  // I'd like this to be the task that ExecutorService runs.

System.out.println(name);

}

这是有可能实现的吗？

最接近的匿名内部类:

for (int i = 0; i < 10; i++) {
    final int x = i;
    futures.add(es.submit(new Runnable() {
        @Override public void run() {
            namePrint(x + "name");
        }
    }));
}
