What is Generics in #Java

Generics in Java is a feature that allows you to define classes, interfaces, and methods that can work with different types of objects. It is a way to make your code more flexible, reusable, and type-safe.

With generics, you can define a class or method that works with a specific type of object, such as a List of Strings. Then, you can reuse that code with different types of objects, such as a List of Integers or a List of custom objects.

Generics provide several benefits, including:

Type safety: With generics, you can catch type mismatches at compile time rather than at runtime, which can help you avoid errors and improve the robustness of your code.

Code reuse: With generics, you can write generic classes and methods that can be reused with different types of objects, which can help you save time and reduce code duplication.

Expressive code: Generics can make your code more expressive and readable by providing type information at the point of use, rather than requiring you to cast objects to the correct type.
