com.zaranux.client.java.io.PrintStream
A PrintStream adds functionality to another output stream, namely the ability to print representations of various data values conveniently. Two other features are provided as well. 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. Optionally, a PrintStream can be created so as to flush automatically; this means that the flush method is automatically invoked after a byte array is written, one of the println methods is invoked, or a newline character or byte ('\n') is written.
All characters printed by a PrintStream are converted into bytes using the platform's default character encoding. The {@link PrintWriter} class should be used in situations that require writing characters rather than bytes. @author Frank Yellin @author Mark Reinhold @since JDK1.0
