Generally speaking, we can say that array types are covariant in Java. We’ll look at examples of covariance ... class Generic<T> { T data; void write(T data) { this.data = data; ...

This example showcases the basic implementation and usage of generics in Java, highlighting ... can create reusable and type-safe components with different data types, enhancing code reusability ...

Even the most complicated classes in Java can be flattened down to nothing more than the set of primitive data types they represent. But primitive types aren’t objects, and that presents a problem.
