Array types in Java are not implicitly contravariant, but they can be explicitly contravariant , just like generic types. I’ll offer some examples later in the article.

Take your coding to the next level by learning advanced programming with generics. Here's how to use generic methods with type inference, type parameters, and wildcards in your Java programs.

Casting down to a smaller data type is an unsafe cast because it has the potential for losing precision. However, most Java developers are rarely satisfied without being told why, so despite the fact ...
