How to Array Matrix 1-by-8 Pass to java method error:No method with matching signature found for class?

Hi,

 On Matl-lab Part :

matrix =[1,2,3,4,5,6,7,8]; % example 1-by-8 dimension
 list=java.util.ArrayList();
 for k=1:length(matrix)
  list.add(int32(matrix(k)));
  end
  training = MainMethod;
 training.list_method(list.add(int32(matrix(k))));

On Java Part
public void list_method(List<Integer> points){

//Here I have Expect points result like [1,2,3,4,5,6,7,8]

recordedSample.getMatrix().add(points);//Sample Class object 
}
Note: From java Code Method arguments replaced List Integer to Double[] (array) also i have got error same .please let me know how i can solve this issues.?
