Generic constructors can use generics to mutate some parameters whose references aren't retained, as syntax is
NonGeneric(T obj, List list) {
list.add(obj);

Generic methods are methods that introduce their own type parameters. This is similar to declaring a generic type, but the type parameter's scope is limited to the method where it is declared.
The wildcard can be used in a variety of situations: as the type of a parameter, field, or local variable; sometimes as a return type.
Wildcard is a special actual parameter for the instantiation of generic (parameterized) types. It can be used for the instantiation, not in the definition of a generic unit.
This example demonstrates you to create a generic class that can compute the average of an array of numbers of any given type (as in example only integer and float).
This example shows the implementation of generic class with two parameter-type.
But here we have created the object of only one type.
This example demonstrates you the functionality of a Generic class and a non-Generic class that are equivalent to each other.
Here class NonGen is similar to Gen but does not use generics.
This example demonstrates that how to create a generic class with a type-parameter.
Generic classes can hold the object of any class and where a type variable is unqualified identifier.
