PrintWriter class methods in Java

java.io.PrintWriter

Prints formatted representations of objects to a text-output stream. This class implements all of the print methods found in PrintStream. It does not contain strategies for writing raw bytes, for which a program should use unencoded byte streams.

Unlike the PrintStream class, if automatic flushing is enabled it will be done only when one of the println, printf, or format methods is invoked, rather than whenever a newline character happens to be output. These methods use the platform's notion of line separator rather than the newline character.

Implemented Interfaces:

Closeable

Flushable

Appendable

AutoCloseable
