Collecting Objects

  • Jeff Friesen


Applications often must manage collections of objects. Although you can use arrays for this purpose, they are not always a good choice. For example, arrays have fixed sizes, making it tricky to determine an optimal size when you need to store a variable number of objects. Also, arrays can be indexed by integers only, which make them unsuitable for mapping arbitrary objects to other objects.
