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. Create a new Eclipse project named Lab_Project_26. Then, 1. download the JavaArrayLists.java source code file to the project folder 2. in Eclipse, import/open the source code file for editing 3. enter your name in the comment block near the top of the file 4. add the required code as described below The main method declares and creates an ArrayList with the identifier names that can hold strings. It also prints out the ArrayList. When we compile and execute this code, we see that the ArrayList is empty: []. Complete the following tasks by adding code to this skeleton program. If you are asked to print a value or an array list, provide a suitable label to identify it when it is printed (e.g., last name: Harry, or names: []). a. Call the ArrayList's add() method to enter the following names in sequence: Alice, Bob, Connie, David, Edward, Fran, Gomez, Harry. Print the ArrayList again. b. Call the ArrayList's get() method to retrieve and print the first and last names. c. Print the size() of the ArrayList. d. Use size() to help you print the last

b. Call the ArrayList's get() method to retrieve and print the first and last names. c. Print the size() of the ArrayList. d. Use size() to help you print the last name in the list. e. Use set() to change "Alice" to "Alice B. Toklas". Print the ArrayList to verify the change. f. Use the alternate form of add () to insert "Doug" after "David". Print the ArrayList again. g. Use a loop (instead of a single call to System.out.println) to print each name in the ArrayList. h. Create a second Array List called names2 that is built by calling the ArrayList constructor that accepts another ArrayList as an argument. Pass names to the ArrayList constructor to build names2. Then print the ArrayList again. i. Call names. remove(0) to remove the first element from the original ArrayList. Print names and names2. Verify that "Alice B. Toklas" was removed from names, but not from names2.
