                    while(sc1.hasNext())

                        {

                            System.out.println("\t"+sc1.next());

                        }

                    sc1.close();

                    System.out.print("\tEnter a Sentence : ");

                    St=sc.nextLine();

                    sc1=new Scanner(St).useDelimiter(",");   

                    System.out.println("\n\tUser Defined Delimiter :\n");                    

                    while(sc1.hasNext())

                        {

                            System.out.println("\t"+sc1.next().trim());
