_{Array lists are objects that, like arrays, provide you the ability to store items sequentially and recall items by index. Working with array lists involves invoking ArrayList methods, so we will need to develop some basic skills. Let's start with the code below: The main method imports java.utii.ArrayList and creates an ArrayList that can hold strings by using the new command along with the ArrayList default constructor. It also prints out the ArrayList and, when it does, we see that the list is empty: [ ]. Create a new NetBeans project with the skeleton program shown above. Then, complete the following tasks by adding code to this skeleton program. If you are asked to print a value, provide a suitable label to identify it when it is printed. Invoke the ArrayList method add (string s) to enter the following names in sequence: Alice, Bob, Connie, David, Edward, Fran, Gomez, Harry. Print the ArrayList again. Use the ArrayList method string get (int index) to retrieve and print the first and last names. Remember that the first name is at index 0, the last name at the index = list size - 1 Print the size () of the ArrayList. Use ArrayList method int size () to help you print the last name in the list. Use ArrayList method string set (int index, string name) to change "Alice" to "Alice B. Toklas". Print the ArrayList to verify the change. Use the alternate form of the ArrayList method add (int index, string name) to insert "Doug" after "David". Print the ArrayList again. Use a for-each loop to print each name in the ArrayList. Create a second ArrayList called names2 that is built by calling the ArrayList constructor that accepts another ArrayList as an argument. Pass names to the constructor to build names2. Then print the ArrayList. Call ArrayList method string names.remove (0) to remove the first element. Print names and names2. Verify that Alice B. Toklas was removed from names, but not from names2.}
