Documents that changes to the specification made between Java SE 15 and Java SE 16. This document includes descriptions of those new features and enhancements that are also changes to the specification. The descriptions also identify potential compatibility issues that you might encounter when migrating to JDK 16.

A BufferedInputStream adds functionality to another input stream-namely, the ability to buffer the input and to support the mark and reset methods. When the BufferedInputStream is created, an internal buffer array is created. As bytes from the stream are read or skipped, the internal buffer is refilled as necessary from the contained input stream, many bytes at a time.The mark operation remembers a point in the input stream and the reset operation causes all the bytes read since the most recent mark operation to be reread before new bytes are taken from the contained input stream. JUnit (3.0) test cases within test source folder.
