  % code
public static void recordSample(List<Integer> points){
recordedSample.getMatrix().add(points);//Sample class object Getter Method
}
end
Below I have Matlab Code :

if true
  % code
 for i=1:20
 matrix{1:i}=[33,22,6544,3335,23,544,5,2] %1-by-8 Matrix values
   clear java;
    import edu.lipreading.*;%Package
    training = TrainingPanel;%Java Class
    javaMethod('recordSample',training,matrix{1:i}); %Error reference to be cleared variable
end
