Quick Answer
Generics add compile-time type safety to collections and algorithms. Without generics: List stores Object, need casting, ClassCastException possible at runtime. With generics: List only holds Strings, no casting needed, wrong types caught at compile time. Write generic methods and classes with type parameters: , , . Type erasure means generics exist only at compile time.
