Any way to extend two or more classes in java?

Question

I know that Java does not allow us to extend more than one class. I know that interfaces also exist and I don\'t want to use them this time. Is there some kind of trick or w

Answer 1

To avoid diamond problem Java does not support Multiple Inheritance through classes but it supports using interfaces. So you may use Association Relationship. e.g.

Class A {}
Class B {}
Class C implements SomeInterface {
  A a;
  B b;
  // setter getter for a and b and other methods
}
