How to use Java Generic Class in MATLAB?

I am new for MATLAB, I would like to use a java generic class in MATLAB.

OS: Windows 7 64 bit, MATLAB R2013a, Java version 1.6.

On Java Part:

public  List<List<Integer>> last=new ArrayList<List<Integer>>();
    public void list_method(List<Integer> points){
    last.add(points);
    recordedSample.getMatrix().add(last); //Sample class object
}

On MATLAB Part:

list =java.util.ArrayList();
while(1)
    matrix = [right_lip_x;right_lip_y;left_lip_xy;left_lip_yx;upper_lip_x;upper_lip_y;bottom_‌​lip_x;bottom_lip_y]; %here 1-by-8 matrix

for k=1:length(matrix)
    list.add(int32(matrix(k)));
    end 
end

I would like expected result list like : [1,2,3,2,2,2,2,1] [442,22,2,2,2,2,4,12] etc..

Note : Please look at my reference link Expected Result another result using Java Generic Class I could not understand, please let me know?
