---

Generics is a handy tool in Java that greatly increases the maintainability of your code by allowing you to reuse code, using the same class or method with different types of data. Furthermore, generics also convert runtime checks to compile-time checks, making your code less error-prone.
In this course, learn how to use generics in Java to write reusable and maintainable code, exploring why generic code has several advantages over non-generic code.
Get hands-on practice with creating and defining classes with generic type parameters. Investigate how these generic types can be used as types for member variables, input arguments to methods, and return values from methods.
Moving along, implement generic methods where the generic type parameter is associated with the method rather than the class itself.
When you're finished, you'll have a solid foundation in defining and working with generic classes and methods in Java.

Objectives

Generics in Java: Creating Classes and Methods Using Generics discover the key concepts covered in this course list the advantages of writing generic code over non-generic code recall the limitations on code reuse in non-generic classes recall the limitations of using raw objects rather than generic types implement a class with generics for type safety and compile-time checks use generic types as input arguments to methods and return values from methods create non-parameterized objects from generic classes recall the disadvantages of non-generic methods parameterize the class definition to create generic methods parameterize the method definition without parameterizing classes illustrate type inference with parameterized methods summarize the key concepts covered in this course
