run java class in octave -

i'm trying call java object in octave. example, here's java code (square class):

public class square {      private int x;     private int y;      public square(int x, int y)     {         this.x = x;         this.y = y;     }      public double s()     {         return x*y;     } } 

and main class:

public class console {      public static void main(string[] args) {         system.out.println("hello world!");         square kv = new square(3, 4);         double r = kv.s();         system.out.println("result: " + r);     } } 

how can call square class or console class in octave? i've tried following didn't work. tried create javaclasspath javaaddpath("c:\users\user\desktop\javatest\console.jar"). add in javaclasspath.txt paths such ~\console.class, ~\console.java , on.

in octave tried call object obj = javaobject("console") error

error: [java] java.lang.classnotfoundexception: console 

ofcourse tried various "console" parameters "console.class", "console.java", "square", ...
