Question

Please help me finish my code.

Before the final pause in the main function, create an ArrayList of another type such as double, char, short, bool, float, etc. Your choice. Add five data items to your array as we did for the int and string array lists. Print them out with a for loop as we did before. Print out the count and capacity of your new array list.
