Java ByteArrayInputStream is a class that allows an application to read data from a byte array as an input stream. It extends the Java InputStream class and is used when you need to process data that already resides in memory as a byte array rather than from a file or network source. Introduced in Java 1995 with Java 1.0, ByteArrayInputStream is useful in scenarios where you want to simulate input from a byte array, such as processing data from HTTP requests or in-memory buffers.
