Java FileInputStream.close() is a method in the Java FileInputStream class that closes the stream and releases any system resources associated with it. It is important to always close file streams to prevent resource leaks, particularly in applications that deal with multiple files or large amounts of data. Introduced in Java 1995 with Java 1.0, close() is essential for good file management practices.
