使用ExecutorService在一定时间后执行方法

Question

我有以下代码：

        ExecutorService executor = Executors.newSingleThreadExecutor()

        Future<String> future = executor.submit(new Callable<String>() {
            @Override
            String call() throws Exception {

                stream.filter(fq)

                return null
            }
        })

        try {

            future.get(4, TimeUnit.MINUTES)

        }

一旦4分钟结束，我想执行另一种方法。我会把这段代码放在哪里？

Answer 1

抓住try { future.get(4, TimeUnit.MINUTES) } catch(TimeoutException e) { //call your method code here, it will be called only if the operation times out myMethod(); } 并将您的代码放入catch块。
