Generics in Java, integrated into Object-Oriented Programming (OOP), represent a set of typing rules that allow operations on multiple data types. With the introduction of symbols like T (Diamond Operators), Java provides the opportunity to define parameterized types, thus ensuring typological safety during compilation. These concepts, in harmony with inheritance and other pillars of OOP, manifest through generic classes, generic methods, and the use of wildcards. By utilizing generics, developers can enjoy increased flexibility while preserving the integrity and robustness of the code.
