It performs type checking when elements are added into the collection List coffeeLst = new ArrayList() Declare a List (List of String) implemented by an ArrayList // The compiler is informed about the type of objects in the collection via. JDK 5 List with Generics, implemented by an ArrayList This allows the compiler to perform type-checking when elements are added into the collection at compile-time to ensure type-safety at runtime. When you construct an instance of these generic types, you need to provide the specific type of the objects contained in these collection, e.g. The indicates that the interfaces are generic in design. The class is the most commonly used implementation of List. The interface is the most commonly used data structure of the Collection Framework, which models a resizable (dynamically-allocated) array supporting numerical index access. Generic Collection Framework (JDK 5) by Examples Example 1: List ( List of Strings) Implemented by ArrayList The classes and interfaces for the Collection Framework are kept in package java.util. You need to refer to the JDK API specification while reading this chapter.
