Generics is the new feture added in the JAVA5.0. It feature
is useful in some broad applications when we are writing any
database insertion logic for the same type of Object.
suppose we have to insert a list of Employee Object this
will be declared as List<Employee> or suppose we have a list

List<Long>, Similarly List<String>, List<Integer>. The
generics class are used by Wrapper classes or any other
classes. Most useful in ORM technologies also.
