                     {
                        case 1:
                           System.out.println("One");
                        break;

                           System.out.println("Two");

                        break;
                        case 3:
                           System.out.println("Three");

                        break;
                        case 4:
                           System.out.println("Four");

                        break;
                        case 5:
                           System.out.println("Five");

                        break;
                        case 6:
                           System.out.println("Six");

                        
                        case 7:
                           System.out.println("Seven");

                        break;
                        default:

                            System.out.println("Error");
                        break                    }
            7    Rewrite the following code using conditional operator. (_?_:_)

                        if(Total>=50)

                                        Show=’Y’;

                        else

                                         Show=’N’;

      while(m>0)
      {
             if(m<10)
                  break;
             m=m-10;
