它是多重继承吗？如果不是为什么？(Is it a Multiple Inheritance?If not why?)

public interface A {
    class Aclass {
        int constants = 100;
        public void display()
        {
            System.out.println("Inside A");
        }
    }
    public void display();

}
public interface B {
    class Bclass {
        int constants = 130;

        public void display() {
            System.out.println("Inside B");
        }
    }
    public void display();
}

public class MultipleInheritance implements A, B {

    @Override
    public void display() {
        A.Aclass a = new A.Aclass();
        System.out.println(a.constants);
        B.Bclass b = new B.Bclass();
        System.out.println(b.constants);
    }

    public static void main(String args[]) {

        new MultipleInheritance().display();
    }
}
 
 虽然它是通过接口而不是通过上下文中的具体类而不是继承任何东西，但仍然不是代码重用，即使保持内部类很难但仍然充当多重继承请用内存表示清除如果可能的话。 

public interface A {
    class Aclass {
        int constants = 100;
        public void display()
        {
            System.out.println("Inside A");
        }
    }
    public void display();

}
public interface B {
    class Bclass {
        int constants = 130;

        public void display() {
            System.out.println("Inside B");
        }
    }
    public void display();
}

public class MultipleInheritance implements A, B {

    @Override
    public void display() {
        A.Aclass a = new A.Aclass();
        System.out.println(a.constants);
        B.Bclass b = new B.Bclass();
        System.out.println(b.constants);
    }

    public static void main(String args[]) {

        new MultipleInheritance().display();
    }
}
 
though it's through interface and not through a concrete class in context to which you are not inheriting anything but still is it not a code reuse even though maintaining a inner classes will be difficult but still it acts as a multiple-inheritance please clearify with memory representation if possible.
