The Java compiler includes a type inference algorithm that examines each generic method invocation and corresponding declaration to figure out the invocation’s type argument (s).

Java generic classes are compiled into bytecodes, assuming java.lang.Object for all type parameters (or, alternatively, a more specific class constraint). This is known as "type erasure".

Generics not only let you create more flexible classes, they make inheritance more flexible, also. To pick the right inheritance mode when inheriting from a generic, though, you must know what you're ...

Since Java 21, wrapper classes have played an increasingly sophisticated role in Java’s type system. Here’s everything you need to know about updates for virtual threads, pattern matching, and ...
