How to Pass Sprintf result to Java Method arguments List<Integer>points Error:No method 'list_method' with matching signature found for class?

Hi,

     On Matlab Side i have code like that :

     if true
        % code
    matrix =[33,122,3,2,2,3,2,4];
    outsprintf=sprintf('%d,',matrix);
    outsprintf=sprintf('[%s\b]',outsprintf);
    disp(outsprintf);
   import edu.lipreading.*;
      training = MainMethod; //Main Java Class Name
      training.list_method(outputString);
      end
  result like :
  outsprintf
  [6,28,117,28,48,1,48,59] ,[27,45,94,45,70,13,70,62],[14,44,139,44,71,1,71,66] ,[4,32,119,32,72,2,72,65] etc..

*On Java Code Part*
public static  void list_method(List<Integer> points){
Sample sample = new Sample();//Class object
sample.getMatrix().add(points);
}

 when i have run mat-lab I have got Error like :

No method 'list_method' with matching signature found for class
