System.out.print(i+ " ” );
                      }
                   Ans.   -2 -4 -6 -8 -10
                    9.   Convert the for loop to a while loop.

                     int a;
                     for (a=2; a<=10;)
                     {
                            a++;
                         System.out.print (a+ " : ");
                     }
                   Ans.  int a;
                      a=2;
                      while(a<=10)
                      {
                            a++;
                         System.out.print(a+ " : " );
                      }
                    10.   Print the output of the program of question 9:
                   Ans.   3 : 4 : 5 : 6 : 7 : 8 : 9 : 10 : 11 :
                    11.   Convert the do-while loop to a for loop.
                      int i=1;
                      do
                            {
                                  System.out.println(i+2);

                                  i+=2;
                            }while(i<5);
                   Ans.   for(int i=1; i<5; i+=2)
                        {   System.out.println(i+2);  }
                    12.   Convert the while loop to a for loop.
                     int n=123, s=0;
                     while(n>0)
                     {
                     s=s+n%10;
                     n=n/10;
                     }
                     System.out.println(s);
                   Ans.   int s=0;
                      for(int n = 123; n>0;)
                      {
                      s=s+n%10;
                      n=n/10;
                      }
                      System.out.println(s);
