va code  12. Given an existing ArrayList named contactList, find the number of contacts in the ArrayList and store it in the existing variable named numContacts.

in java programming answer the following: Given an array called myArr (created as ArrayList<T>) and contains the {1,2,3,4,5,6,7}. (a) what would be the contents of this array after myArr.add(10). b) write the content of myArr after myArr.add(4, 11);

This is needed in Java   Given that an ArrayList of Strings  named nameList has already been created and names have already been inserted, write the statement necessary to delete the name at index 15.
