Course details
Generics in Java are popular and widely used in all kinds of project development—Core Java projects, web application projects, web services, and more. It’s an indispensable capability in the Java language and provides the power of eliminating errors at compile time itself instead of resulting in runtime problems. In this course, Ketkee Aryamane goes hands-on with generics in Java. She starts with the fundamental concepts, terms, and rules and naming conventions in generics, then covers generic classes and methods. Ketkee then takes a deeper dive into generics, covering topics like generic class hierarchies, wildcard arguments, and restrictions on generics. If you’re a developer looking to save time by eliminating runtime issues and making more readable code, join Ketkee in this course.
