What is used to read a stream of bytes in a program?

Java

In a program, a stream of bytes is typically read using input/output (I/O) classes or functions provided by the programming language's standard library. For example, in Python, the open() function can be used to open a file in binary mode, and then methods like read(), readline(), or readlines() can be employed to read bytes from it. In Java, classes like FileInputStream or BufferedInputStream are used to read byte streams. These tools facilitate efficient reading and processing of byte data in various applications.
