How has BufferedInputStream / BufferedReader changed in recent Java versions?

In recent Java versions, BufferedInputStream and BufferedReader have seen enhancements that improve performance and usability. These classes allow for efficient reading of data streams by buffering input, thus minimizing the number of I/O operations. With updates in Java 9 and later, features such as new methods for better handling of bytes and characters have been introduced.

Specifically, the introduction of methods such as markSupported() and improved handling of character encodings in BufferedReader enhance the way developers interact with input streams. Additionally, there are new constructors that allow for better control over buffer sizes and performance optimizations.
