PrintWriter prints formatted representations of objects to a text-output stream. In other words, you can say it enables to write formatted data to a writer. It implements all of the print methods found in PrintStream and does not contain methods for writing bytes. For instance, writing int, long and other primitive data formatted as text.

		PrintWriter pw = new PrintWriter("c:/newfile.txt");
		pw.println("This is the use of PrintWriter class");
		pw.println(1234);
		pw.close();
	}
}
