The Java Generics programming is included in J2SE 5 to administer with type-safe things. Generics in Java are related to templates in C++. The purpose is to concede class (String, Integer, and user-defined sorts) to denote a parameter to designs, types, and interfaces. For instance, states like HashMap, HashSet, ArrayList, etc utilize generics pretty well. We may utilize them for each kind. We may write a design/class/interface already and apply for all kind we require. Before Generics, we needed to typecast.
