Hi,

I have download and installed Java 1.6.0_35-b10, so without while loop if i list add working , but when i have used while loop then i am getting java.lang.OutOfMemoryError: Java heap space.?

On Mat-lab Part Side

list=java.util.ArrayList();
for k=1:length(matrix)
    list.add(int32(matrix(k)));
    end
import edu.lipreading.*;
     training = MainMethod;
     training.list_method(list);

on Java Class Part Side

public void list_method(List<Integer> points){
while(true){
Sample sample = new Sample();
sample.getMatrix().add(points);
}
}

I am getting error when i am run my mat-lab application.?

java.lang.OutOfMemoryError: Java heap space
  at java.util.Arrays.copyOf(Arrays.java:2734)
  at java.util.Vector.ensureCapacityHelper(Vector.java:226)
  at java.util.Vector.add(Vector.java:728)
  at edu.lipreading.MainMethod.onRecord(MainMethod.java:40)
  at edu.lipreading.MainMethod.list_method(MainMethod.java:26)

Note :please let me know where i have done mistaken ?because from input web cam video processing various coordinates values in list 1-by-8 matrix .?
Example :matrix =[1,2,3,4,5,6,7,8] ,[554,33,2,2,544,2332,2,2] etc..
Note 2: I have followed result link also ,but i cannot resolved my issue please let me know .

You mean kind of "I want a two vector outputs, but get only one"? It kind of seems fair enough to me. Are you sure that your webcam returns the output you want from it. I seems to me that one 1-by-8 vector is returned for every reading.

Thanks for reply me . yes from input web cam video i have 1-by-8

On Mat-lab Part

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]; %1-by 8 vector values 
list=java.util.ArrayList();
for k=1:length(matrix)
list.add(int32(matrix(k)));
end
import edu.lipreading.*;
training = MainMethod;
training.list_method(list);

On Java Part

public void list_method(List<Integer> points){
Sample sample = new Sample();
//Sample Class having private List<List<Integer>> matrix; Getter and Setter Method
sample.getMatrix().add(points);
}
My Result showing like :Sample [id=web cam 10:41:06 11/03/2014, matrix=[136, 41, 1, 41, 77, 8, 77, 72]] Sample [id=web cam 10:41:12 11/03/2014, matrix=[170, 49, 10, 49, 88, 10, 88, 84]] etc..

Actually I want to Expected result like Sample [id=web cam 10:41:12 11/03/2014, matrix=[136,41,1,41,77,8,77,72],[170, 49, 10, 49, 88, 10, 88, 84]] please let me know how i can get result?.
