Streams including default System streams not finished

In Java, 3 streams are created for us automatically. All these streams are attached with the console.

1. System.out: standard output stream

2. System.in: standard input stream

3. System.err: standard error stream

OutputStream class (same for InputStream class)

OutputStream class is an abstract class. It is the superclass of all classes representing an output stream of bytes. An output stream accepts output bytes and sends them to some sink.
