java - 如何在不使用ExecutorService的情况下实现固定线程池

Question

我有这样的代码块

   static ExecutorService executor = Executors.newFixedThreadPool(4);
   Runnable worker = new CsvToJavaObject(newFilePath);
   executor.execute(worker);

我想将线程数限制为 n(4) 并且不使用 Executor Service。我该怎么做？

Answer 1

ThreadPoolExecutor 怎么样？

ThreadPoolExecutor threadPool = new ThreadPoolExecutor(5, 5, 5, TimeUnit.SECONDS, new LinkedBlockingQueue<Runnable>());
