extending properties of a class if the other class is already extended in java

Question

I have created a class with some methods which is extended already with UnicastRemoteObjects

public class AccountAuthorizationFilter extends UnicastRemoteObject implements Serializable{//methods}

I have another class which is extended by another class

public class DRMSServerImplementation extends DRMSInterfacePOA{}

How to extend the methods of AccountAuthorizationFilter into DRMSServerImplementation ?? Any alternative possibilities excluding the use of objects of that class?

Answer 1

AccountAuthorizationFilter和DRMSServerImplementation类可以实现另一个接口，其中包含您需要在两个类中使用的方法。
