First step in java.nio

Question

I'm moving the first steps in java and I met this kind of package.

Why was the package java.nio introduced and what does'nio' stand for?

Answer 1

NIO stands for non-blocking input/output or new input/output.

It was first introduced in Java 1.4, but it has been updated in new versions of Java. Main difference from classic Java IO are:

1. in NIO you are using Channels and Buffers instead of byte and character Streams
2. NIO is non-blocking, which means that thread can do something else while channel is reading data
3. NIO provides selectors used for monitoring multiple channels for events at once
