What is Generic Classes Java?
Generic classes in Java are classes that allow you to define type parameters, enabling you to create a single class definition that can operate on different data types. This feature enhances code reusability and type safety by allowing developers to specify the data type a class works with when it is instantiated. For example, a generic class can be defined as class Box<T>
, where T
is the type parameter. When you create an instance of Box
, you can specify a particular type, like Box<Integer>
or Box<String>
.
