1) Completely unclear what you mean
    Load a method of an interface? How do you do that?
2) Answering questions by e-mail is not how it works here at EE.

I don't understand what you mean by 'load', but I will try to answer whatever I have understood from your question:

1. It is not important to implement (provide the code for) all methods defined in the interface - but if you do that, then your class has to be declared as abstract.

2. All methods that you implement (which were declared in the interface) must be given the 'public' modifier in the implementing class.

And secondly, DON'T give e-mail IDs in your question-pages. We're supposed to answer your questions here, not on mails. Sometimes, the moderators don't like it if they see e-mail IDs on question-pages.

"if you do that" == "NOT implementing all methods defined in the interface"

>> DON'T give e-mail IDs in your question-pages.
It's begging for spam too.

If not clear yet:

say, you have a class Xyz implements Interf

that means that you promise to implement all methods defined in 'Interf' in 'Xyz'
     in order to make 'Xyz'  "look like an Interf".

If you do not implement all those methods, your class is not going to look like an 'Interf' at all
     and unacceptable for all references to 'Interf'.

So, if somewhere there is a variable:

       Interf  pointer;

JAVA demands that it will always point at a 'Interf' look-alike.

Do you understand that?

;JOOP!
