Generics are a programming feature that allows developers to create classes, interfaces, and methods with a placeholder for the data type. This means you can write code that works with any data type while maintaining type safety. For example, a generic list can store integers, strings, or any other type without needing to write separate code for each one. Using Generics helps reduce code duplication and increases reusability. It also makes the code easier to read and maintain, as the data types are specified only once. Overall, Generics enhance flexibility and efficiency in programming.
