Everything about Generics in Java

Features of the Java programming language

Generics are a facility of generic programming that were added to the Java programming language in 2004 within version J2SE 5.0. They were designed to extend Java's type system to allow "a type or method to operate on objects of various types while providing compile-time type safety". The aspect compile-time type safety required that parametrically polymorphic functions are not implemented in the Java virtual machine, since type safety is impossible in this case. Wikipedia →
