****************************************************************************************
The Java Generics allows us to create a single class, interface, and method that can be used with different types of data (objects). This helps us to reuse our code. Note: Generics does not work with primitive types ( int , float , char , etc).
What is the use of generics in Java?
Java Generics helps the programmer to reuse the code for whatever type he/she wishes. For instance, a programmer writes a generic method for sorting an array of objects. Generics allow the programmer to use the same method for Integer arrays, Double arrays, and even String arrays.
