Write the statement to declare an ArrayList named myVals with a capacity of 15 items. Explain the importance of capacity when working with an ArrayList.
What will be an ideal response?
ArrayList myVals = new ArrayList(15);
An ArrayList's capacity is the number of items it can hold without having to increase its size. An ArrayList's capacity is greater than or equal to its size. It is more efficient to create an ArrayList with a larger capacity if you know you will need a specific number of items.
