Summary

Override write(byte[]) and add writeBytes.

Problem

java.io.PrintStream was supposed to override methods not to throw IOException as indicated in the class documentation:

Unlike other output streams, a PrintStream never throws an IOException; instead, exceptional situations merely set an internal flag that can be tested via the checkError method.

The method write(byte[]) of java.io.FilterOutputStream was, however, not so overridden. The method is therefore documented as throwing IOException but never does so.

Also, there is no write method which has only a byte array parameter and which is not declared to throw IOException. Callers are thus obliged in this scenario to write a try-catch block even though IOException will never be thrown.

Solution

Override write(byte[]) adding clarifying documentation while retaining the existing behavior, and add writeBytes.
