Lifetime of Java Variables

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.

Syntax of PrintStream

public class PrintStream
extends FilterOutputStream
implements Appendable, Closeable
