Java DataInputStream is a class that allows an application to read primitive data types (like Java int, Java float, Java double, etc.) from an input stream in a portable way. It is typically used to read binary data that is stored in files or transmitted over a network. Introduced in Java 1995 with Java 1.0, DataInputStream is part of Java's java.io package and provides methods like Java readInt() and Java readDouble() to read data in a machine-independent manner.
