===Multiple inheritance===

In a [[programming language]] that does not support [[multiple inheritance]] of base classes, wrapper functions can be used to simulate it. Below is an example of part of a [[Java (programming language)|Java]] class that "inherits" from LinkedList and HashSet. See [[Method (computer programming)|Methodmethod]] for further implementation details.

<syntaxhighlight lang="Java">

public class Test implements LinkedList, HashSet {

@Override

// contains data members and data methods

@Override

// covariant return

//contains data members and data methods

//covariant return

}

</syntaxhighlight>
