如何在Java中阻止线程在阻塞读取操作中等待？ [英] How to stop a thread waiting in a blocking read operation in Java?

问题描述

我有一个执行以下代码的线程：

I have a thread that executes the following code:

public void run() {
    try {
        int n = 0;
        byte[] buffer = new byte[4096];
        while ((n = in.read(buffer)) != -1) {
            out.write(buffer, 0, n);
            out.flush();
        }
    } catch (IOException e) {
        System.out.println(e);
    }
}

其中 in 是 System.in 。我怎样才能优雅地停止这样的线程？关闭 System.in ，也不使用 Thread.interrupt 似乎无法正常工作。

where in is System.in. How can I stop such thread gracefully? Neither closing System.in, nor using Thread.interrupt appear to work.

推荐答案

这是因为读取System.in（InputStream）是一个阻塞操作。

This is because reading System.in (InputStream) is a blocking operation.

看这里是否可以从具有超时的InputStream读取？
