Difference between Inheritance and Composition

Question

Are Composition and Inheritance the same? If I want to implement the composition pattern, how can I do that in Java?

Answer 1

Inheritance between two classes, where one class extends another class establishes "IS A" relationship.

Composition on the other end contains an instance of another class in your class establishes "Has A" relationship. Composition in java is is useful since it technically facilitates multiple inheritance.
