Answer 1

I did it by the following way. number and name are two arraylist. I have to sort name .If any change happen to name arralist order then the number arraylist also change its order.

public void sortval(){

        String tempname="",tempnum="";

         if (name.size()>1) // check if the number of orders is larger than 1
            {
                for (int x=0; x 0)
                        {

                            tempname = name.get(i);

                            tempnum=number.get(i);


                           name.set(i,name.get(i+1) );
                           name.set(i+1, tempname);

                            number.set(i,number.get(i+1) );
                            number.set(i+1, tempnum);


                        }
                    }
                }
            }
