Quick Answer
Generics allow you to write type-safe code that works with any type without casting. List instead of raw List. The compiler catches type mismatches at compile time. Type parameters are erased at runtime (type erasure) - the JVM sees raw types. Benefits: no need for explicit casting, compile-time type safety, reusable algorithms that work on any type.
