WebGenerics. In modern typed programming languages, a type can be parametrized by another type, a feature sometimes known as parametric polymorphism. In Java, this takes the form of so-called generics, introduced in Java 5. WebA pair of concrete classes in the JDK in a parent-child relationship are ArrayList and LinkedList, where LinkedList is the child class of List. One overloaded method is add (), which allows the insertion of an element to the end of the list. Another polymorphic method is get (), which returns the element at the specified index in the list.

WebSupport for generics is not an essentially object-oriented idea, and was not originally part of Java, having been first introduced in Java 5. Collections The main motivation for adding parametric polymorphism and generic types to Java was the Java Collections Framework. WebThe most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object. Any Java object that can pass more than one IS-A test is considered to be polymorphic. In Java, all Java objects are polymorphic since any object will pass the IS-A test for their own type and for the class Object.
