我应该关闭使用 java.nio.file.Files.newInputStream 创建的流吗？
Should I close Streams created with java.nio.file.Files.newInputStream?
在流教程中，没有提到关闭从 Files.newInputStream( path ) 获得的流。只有一些晦涩：
Whether the returned stream is asynchronously closeable and/or
interruptible is highly file system provider specific and therefore
not specified.
在此上下文中，"asyncronously" 是什么？如果我显式关闭流，或者另一个线程异步关闭流？
您一定要关闭获得的 InputStream，就像所有其他人一样。术语 "asynchronously closeable" 指的是在另一个线程因 I/O 操作而阻塞时关闭流的能力。
来自 InterruptibleChannel 文档：
A channel that implements this interface is asynchronously closeable: If a thread is blocked in an I/O operation on an interruptible channel then another thread may invoke the channel's close method. This will cause the blocked thread to receive an AsynchronousCloseException.
您可以使用新的 try with resources 选项方便地执行此操作。
try(/*initialize resources here*/)
{
}
它们会在 try 块之后自动关闭。根据需要添加捕获。
