Examples of PrintStream

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
java.io.PrintStream
PrintStream is a class which takes an OutputStream and provides convenience methods for printing common data types in a human readable format on the stream. This is not to be confused with DataOutputStream which is used for encoding common data types so that they can be read back in. No IOExceptions are thrown by this class. Instead, callers should call checkError() to see if a problem has been encountered in this Stream.
