Answer 2

Option A) Streams

Streams of these is used to perform all input and output operations in Java.

• With its I/O package, Java includes a variety of Streams that make it easier for the user to carry out any input-output tasks. For complete I/O operation execution, these streams support all object, data-type, character, and file kinds.
• The abstract superclass that represents an output stream of bytes is the OutputStream class from the java.io package. OutputStream is not useful by itself because it is an abstract class. However, data can be written via its subclasses.
• The input is processed and the output is created using Java I/O (Input and Output). Java makes advantage of the stream idea to speed up I/O. All of the classes needed for input and output operations are included in the java.io package.
• Java specifies two different stream types. It's them, A convenient method for processing byte input and output is the byte stream. Character Stream: It offers a practical method for managing character input and output.
