Examples of java.io.PrintStream

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.
