Need help on Java design pattern

Question

Can you suggest some good design pattern for below scenario:

We have multiple vendors, called Company A, B and C. Each company has their own business logic.

"I would like to write some wrapper kind of class, that should decide which company to invoke, override all generic methods and do all operation." Why do you want to do that? This seems to throw away everything you described above it. Anyway, sounds like it might be a Proxy pattern. — Daniel Kaplan, Apr 13 '15 at 20:53

Smells like Strategy Pattern to me: link

Inside interface define method(s) which will be performed by concrete vendors. Concrete vendor have to implement interface and add own implementation of method (strategy).

You may use an interface, CompanyTemplate which will contains all the common methods that should be implemented by company A, B and C -

public interface CompanyTemplate{

   public someCommonMethod();

}

After that A can inplement CompanyTemplate -

public class A implements `CompanyTemplate` {

  public void someCommonMethod(){
     //implementation code
  }  

  //Other methods special only for company for A

}
