1-System is a class which include for input.output and error.

2-Out is static variable which is used for output.

3-And println() is to write output on console.

System.out.println(): while using println() with System.out, it will print on the console.

PrintWriter.println(): PrintWriter can write to other sources than just the console, it can write to an HttpResponse.

With System.out.println(..) we can print to Console.

But System.out internally creates PrintWriter object.So why cant we use 
PrintWriter.println(..) directly to write to console.
