1. What is a generic type?Generics (generics) are parameterized types, applied to classes, interfaces, methods, and can be assigned a type by executing a generic type call, replacing the generic type with the specific type of assignment. The

Java generics (generics) is a new feature introduced in JDK 5 that allows the use of type parameters (types parameter) when defining classes and interfaces. The declared type parameter is replaced with a specific type when used. The most important
