Java generics are primarily designed to enable types to be treated as parameters for classes, interfaces, and methods. This means that you can define a class or method with a placeholder for a type, allowing you to use that type when instantiating the class or calling the method, which in turn leads to type safety and code reusability.

By using generics, you can create classes and methods that work with any data type while still maintaining compile-time type checking. This reduces the occurrence of runtime errors, as the compiler can catch type mismatches before the code is run. Consequently, developers can write more flexible and generic code, making their applications easier to manage and understand.

This capability is particularly beneficial when working with collections, as it allows you to define collections that can hold any type of objects without needing to cast them each time. Overall, the integration of generics into Java significantly improves code quality and developer productivity.
