Java Generics allow you to write a class or method that are parametrized with a type. The most popular usage of generics is undoubtedly the Java SE Collection utilities. Collection interfaces: Collection, List, Set, Map, etc. This requires a type argument be passed to a generic class when it is instantiated or passed when a generic method is called. Just keep in mind that we are abstracting the type of number or String we dealing with, so that when we create we specify what kind we need and it will done in compile time for code efficiency and also preventing . Java Generics: ——————. This is what Maurice Naftalin calls The Get and Put Principle in his Java Generics and Collections and what Joshua Bloch calls The PECS Rule in his Effective Java.

After working with Java for almost 15 years and deep knowledge of Java generics on the class format level I learned something very basic the really, really hard way. General-purpose implementations: ArrayList, LinkedList, HashSet, HashMap, etc. An example interface which shows the usage of generics. The most common examples are container types, such as those in the Collections hierarchy. Generics are a rather difficult subject to grasp as they An ArrayList is a container that is part of the Java Collection Library and it is a generic class that is called with a type argument. The common case for Java generics involves being able to write type-safe algorithms which can be applied to any appropriate data-type.
