Can I limit the methods another class can call in Java?

Question

Let\'s assume I have classes A, B, and C where class C has readable and writable properties:

public class         


        

Answer 1

Although the straight answer is no, another workaround(an ugly one) could be to create two interfaces extending a third(or you could just take an Object as parameter): Reader and Writer, to pass the calling class as a parameter to each function:

public interface Caller;
public interface Reader extends Caller;
public interface Writer extends Caller;


public void increment(Caller c) { 
     if (c instanceof Writer) {
         i++;
     } 
}
