Generics

Generics in java 

Motivation behind Generics-Dealing with casting of objects

The Generics Facility  

Creating a Generic class

Writing a Generic Method

Naming convention in generics

Generics are syntactic sugar - Type Erasure with Generics

Advantage of Generics

Subtyping a generic type

Wildcards in Generics

Generics classes in java vs templates in c++

Restrictions on wildcards in generics

Some mistakes to be avoided with generics:

Beginner's mistake of using Object as type parameter to make method generic

Generic methods: How generic are generic method?

Wildcards in Generics 

Bounded parametric types 

Covariance, contravariance, invariance

Upper bound boundedness in generics

Lower bound boundedness in generics

Multiple bounds in generics

Get and Set principle in generics

Restrictions on wildcards in generics

Expressing dependencies in type parameters : Wildcards vs type parameters

Class objects as type literals

Generic types are not covariant

Type erasure in generics

Making return type of method as generic

Covariant parameter types
