Generics Java

Generics in Java is a powerful feature that allows developers to create classes, interfaces, and methods with a placeholder for types, enabling type-safe operations on objects. By using generics, programmers can write more flexible and reusable code, as they can define a single method or class that works with different data types. This enhances code readability and maintainability while ensuring type safety at compile-time, preventing runtime errors. Generics are commonly used with collections, such as lists and maps, allowing them to hold any type of object while enforcing type constraints, thus improving overall code quality and performance.
