Java FileInputStream.read() is a method in the Java FileInputStream class used to read bytes from a file. It returns the next byte of data or -1 if the end of the stream is reached. This method is used for basic file reading operations, particularly for binary files. Introduced in Java 1995 with Java 1.0, read() is a fundamental method for handling file input and working with raw data streams in Java applications.
