Bounded type parameters restrict the types that can be used as arguments for a generic type parameter. This is achieved using the extends keyword, allowing you to specify that a type parameter must be a subtype of a particular class or interface (or the class/interface itself). Bounded type parameters enhance type safety and enable access …
In Java, Generic classes allow you to write flexible, reusable, and type-safe code by enabling classes, interfaces, and methods to operate on objects of various types while providing compile-time type checking. Generic Classes A generic class is a class that can work with any data type, specified via a type parameter. The type parameter acts …
Generics were introduced in Java with the release of J2SE 5.0 (Java 5) in September 2004. The primary motivation behind this addition was to enable developers to write more flexible and reusable code without sacrificing type safety. Before generics, collections were typically used with Object references, which required explicit casting and carried the risk of …
