  • What is adhoc and pure polymorphism in Java?

    Ad hoc polymorphism is only used within a class. Let's examine the Java code in the example below. A way for defining the same method with the same arguments but multiple implementations is called pure polymorphism. Pure polymorphism is achieved in the Java programming language using the idea of method overriding.

  • What is an example of ad hoc polymorphism in Java?

    Method overloading is one example of ad-hoc polymorphism. For example, you can have two versions of method that appends two items — one that takes two integers and adds them, and one that takes two strings and concatenates them. You know, 2 plus 3 is 5, but “2” plus “3” is “23”.

  • What is the difference between ad hoc and universal polymorphism?

    Universal or parametric polymorphism is another type of polymorphism. Unlike ad hoc, which is based on type, universal polymorphism is type-agnostic. Ad hoc polymorphism is derived from the loose translation of “ad hoc,” which is “for this.” That means the polymorphism relates specifically to certain data types.
  • Ad-hoc polymorphism is a dispatch mechanism: the type of the arguments is used to determine (either at compile time or run time) which code to invoke. Parametric polymorphism refers to code that is written without knowledge of the actual type of the arguments; the code is parametric in the type of the parameters.
