Implementation MVC of problem

fell0206

Everybody, I have some MVC of problem, I reference more information, and I write the Model, the Controller and more than one View, but I don't know my code is consistent with MVC? Please give some help! Thank you~

import java.util.*;

public class Initial {

/\*\*
 \* @param args
 \*/

public static void main(String\[\] args) {
	// TODO Auto-generated method stub
	View v = new View("View");
	View2 v2 = new View2("View2");
	Model m = new Model();
	Controller c = new Controller(m);
	c.add(v);
	c.add(v2);

	v.display();
	v2.display();

	c.showAryList();
}

}

public class Model {
private enum States {
Add, Subtract
};

private States state;

public Model() {
}

public void changeToAdd() {
	this.state = States.Add;
}

public void changeToSubtract() {
	this.state = States.Subtract;
}

public int caculate(int x, int y) {
	int currentInt = 0;
	if (this.state == States.Add) {
		currentInt = add(x, y);
	}

	if (this.state == States.Subtract) {
		currentInt = substract(x, y);
	}

	return currentInt;
}

public int add(int x, int y) {
	return x + y;
}

public int substract(int x, int y) {
	return x - y;
}

}

import java.util.*;

public class Controller {

// private Viewable v;
private Model m;
private List aryList;

public Controller(Model m) {
	// TODO Auto-generated constructor stub
	this.m = m;
	aryList = new ArrayList();
}

public void add(Viewable v) {
	aryList.add(v);
	System.out.println(v.getName() + "add!");
	v.addController(this);
}

public void removeView(Viewable v) {
	aryList.remove(v);
	System.out.println(v.getName() + "remove!");
}

public void sumNumber(Viewable v, int N1, int N2) {
	this.m.changeToAdd();

	if (aryList.contains(v)) {
		((Viewable) this.aryList.get(aryList.indexOf(v))).show(this.m
				.caculate(N1, N2));
	}
	removeView(v);
}

public void substractNumber(Viewable v, int N1, int N2) {
	this.m.changeToSubtract();

	if (aryList.contains(v)) {
		((Viewable) this.aryList.get(aryList.indexOf(v))).show(this.m
				.substract(N1, N2));
	}
}

public void showAryList() {
	for (int i = 0; i < aryList.size(); i++) {
		System.out.println(aryList.get(i).getClass());
	}
}

}

public interface Viewable {
// final String name;
public String getName();

public void addController(Controller c);

public void show(int result);

}

I doubt that anyone will want to wade through your code on the off-chance it might be problematic. The purpose of the forum is to answer questions relating to specific issues not for peer review.
