Implementing methods from an interface but with different parameters

Question

I am looking for a good way to have different implementations of the same method which is defined in an interface but with different parameter types. Would this be possible?

Answer 1

Here's an example of Generics

Database

public interface Database {
    public T createNode(...);
    public void modifyNode(T id, ...);
    ...  
}

Database1

class Database1 implements Database { 
    @Override
    public Long createNode(...) { 
        ...
        long result = // obtain id of created node
        return result;
    }

    @Override
    public void modifyNode(Long id, ...) { 
        ...
        // use id
    }
}

Database2

public class Database2 implements Database { 
    @Override
    public SomeObject createNode(...) { 
        ...
        SomeObject result = // obtain id of created node
        return result;
    }

    @Override
    public void modifyNode(SomeObject id, ...) { 
        ...
        // use id as (SomeObject)id
    } 
}

Btw, don't worry about autoboxing. You are using JDK >= 5 since there are @Override annotations.
