public class Variable {

/*list of variables this variable is connected to. */ Vector neighbors;

/* id of this variable */

public int varID;

/* id of agent this variable belongs to. */

public int agentID;

/** The domain of possible values for this variable. */

Value[] domain;

/** Size of the domain */

int domainSize; public Variable(int agentID, int varID, int domain_s) {

this.agentID = agentID;

this.varID = varID;

domainSize = domain_s;

/* set the domain of the variable to be int values between [0,]. */

domain = new NominalValue[domainSize];

for(int i=1;i

domain[i] = new NominalValue(i);

}

neighbors = new Vector();

} public void addNeighbor(Variable v){ neighbors.addElement(v);

}

public boolean isNeighbor(Variable v){

for(int i=0;i

Variable vv = (Variable) neighbors.elementAt(i);

if(v.equalVar(vv))

return true;

}

return false;

} }

下面是我写的matlab类，主要问题在于addElement()总报错

classdef Variable

%VARIABLE Summary of this class goes here

end

methods

%Class Constructor

function obj = Variable(agentID , varID , domain_s)

import java.util.*;

import problem.*;

obj.agentID=agentID;

obj.varID = varID ;

obj.domainSize = domain_s ;

% set the domain of the variable to be int values between [0,].

obj.domain = problem.NominalValue(obj.domainSize);

for i = 1:obj.domainSize

obj.domain(i)=problem.NominalValue(i);

end

obj.neighbors = Vector();

end

%Class Constructor end

end

method

function addNeighbor(obj,v)

obj.neighbors.addElement(v);

end function bool_isNeighbor = isNeighbor(obj,v)

for i = 0 : neighboors.size()

vv = Variable(obj.neighbors.elementAt(i));

if v.equalVar(vv)

bool_isNeighbor = true ;

return ;

end

end

bool_isNeighbor = false ;

end

end

我现在的问题主要在addElement(v) 这部分，不能把一个对象加入到neighbors数组中，请哪位大牛可以帮忙解决一下呀？真心的是感谢一下呀！
