Generics in Java programming Why use generics? How to use generics for type safety Generics in the Java Collections Framework Examples of generic types in Java Raw types vs. generics Why use generics?

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".

Universal generics would allow Java type variables to range over primitive and reference types, making it easier to extend or reuse code across different types.
