Byte streams

Byte streams, also known as binary streams, are used for reading and writing binary data at the byte level. They deal with data as a sequence of individual bytes, without any interpretation or manipulation of the data. Byte streams are particularly useful for handling non-textual data, such as images, audio, video, or any other kind of binary files.

In most programming languages, byte streams consist of two fundamental operations:

1. Input: Byte streams allow you to read data from a source, such as a file or a network socket, into your program. You can read data in fixed-sized chunks or even one byte at a time, depending on your requirements. Byte streams provide methods to read bytes and byte arrays.

2. Output: Byte streams enable you to write data from your program to a destination, such as a file or a network socket. You can write data in fixed-sized chunks or one byte at a time. Byte streams provide methods to write bytes and byte arrays.

Byte streams are commonly used for tasks such as:

• Reading and writing binary files: Byte streams provide a way to read and write data to and from files in their raw binary form.
• Network communication: Byte streams are used for reading and writing data over network sockets in client-server communication.
• Serialization: Byte streams are employed for object serialization, which involves converting objects into a binary format for storage or transmission.

In Java, some commonly used byte stream classes include InputStream and its subclasses (FileInputStream, ByteArrayInputStream, etc.) for input operations, and OutputStream and its subclasses (FileOutputStream, ByteArrayOutputStream, etc.) for output operations.

Character Streams:

        Character streams, also known as text streams, are used for reading and writing text-based data at the character level. They provide a higher-level abstraction over byte streams by handling character encoding and decoding, allowing you to work with text in a more convenient and portable manner.

Character streams are particularly useful when dealing with text files, processing user input, or transmitting text-based data. They handle the conversion between the platform's default character encoding and the specified character encoding, ensuring that characters are correctly represented.

Character streams offer two fundamental operations:

1. Input: Character streams allow you to read text data from a source, such as a file or a network socket, into your program. You can read data as characters, lines, or even entire files. Character streams provide methods to read characters, strings, or lines of text.

2. Output: Character streams enable you to write text data from your program to a destination, such as a file or a network socket. You can write characters, strings, or lines of text. Character streams provide methods to write characters or strings.

Character streams are commonly used for tasks such as:

• Reading and writing text files: Character streams provide a convenient way to read and write text data to and from files, handling character encoding automatically.
• Text-based communication: Character streams are employed for reading and writing text-based data over network sockets or communication protocols that deal with text.
• Parsing and manipulating text: Character streams are useful for parsing and processing text data, such as extracting information, searching, or manipulating strings.

In Java, some commonly used character stream classes include Reader and its subclasses (FileReader, InputStreamReader, etc.) for input operations, and Writer and its subclasses (FileWriter, OutputStreamWriter, etc.) for output operations.
