About this course

Generics allow us to create generic classes and methods by specifying a type parameter. In this course, you’ll learn about generics in Java, their use cases, and how these topics can help you create scalable, type-safe code. Then you’ll explore the Java Collections framework, which helps overcome the limits of an array and provides more complex functionality to meet different collection needs.

Skills you'll gain

  • Implement generics in Java

  • Use wildcards in your code

  • Implement Sets, Maps, and more

  • The progress I have made since starting to use codecademy is immense! I can study for short periods or long periods at my own convenience - mostly late in the evenings.
