java: inheritance

Question

What are some alternatives to inheritance?

Answer 1

Try Delegation which is also know as Composition

Also found the new alternative as mixin

The mixins are kind of composable abstract classes. They are used in a multi-inheritance context to add services to a class. The multi-inheritance is used to compose your class with as many mixins as you want. For example, if you have a class to represent houses, you can create your house from this class and extend it by inheriting from classes like Garage and Garden. Here is this example written in Scala:

val myHouse = new House with Garage with Garden
