Dynamic arrays, on the other hand, can grow and shrink at runtime. In Java, dynamic arrays are implemented using classes like ArrayList. These classes provide methods to add and remove elements, making them a m
The other generic collection classes that will be studied in this chapter, Vector, Stack, and Hashtable, all deal with objects as if they had no specific type. That is, they treat them as type Object, the root class of all classes in Java. This works fine from one standpoint: you ne...
