InputStream is an abstract class in Java that represents an input stream of bytes. It provides a way to read data from a source in a sequential manner, byte by byte or block by block. It is the base class for all input streams in Java, including FileInputStream, ByteArrayInputStream, and others.
The InputStream class provides several methods for reading data from the stream, such as read(), read(byte[]), and read(byte[], int, int). It also has methods for skipping over bytes in the stream, available(), and closing the stream.
InputStream is designed to be subclassed by other classes that provide specific implementations of input streams. It is an important part of Java's I/O (input/output) system, which is used for reading and writing data to and from files, network sockets, and other sources.
