Java escape sequences and the special characters they represent;

     Backspace 
	     Horizontal tab 
v     Vertical tab 

     New line 
     Backspace 
f     FormFeed 
     Carriage return 
"     Double quote 
\'     Single quote 
\     Backslash 

For example;

   File newFile = new File("C:\myfolder\myfile.txt");
   FileOutputStream newFileOutputStream = new java.io.FileOutputStream(newFile);
   java.io.PrintStream newPrintStream = new java.io.PrintStream(newFileOutputStream);
   newPrintStream.flush();
   newPrintStream.println("This will print a line of text followed by carriage return line feed
");
   newPrintStream.println("so this text will be on a new line when viewed in Notepad
");
   newPrintStream.println("and this text will be
split over two lines
");
   newPrintStream.flush();
   newPrintStream.close();
