how 2D array pass as object in MPJ

Question

I am trying to pass 2d array as object in MPJ library but it gives error at this line

Object sendobject = new Object[1];
sendobject[0] = (Object)g.adjMatrix;  
//Graph g = new Graph();
// adjmatrix is public member of class Graph having detail of 
// connecting nodes to each other

Im currently follow the example of this blog.

I am not sure, why you create an array with one element, but this:

Object sendobject = new Object[1];

does not work. Either you want an array:

Object[] sendobject = new Object[1];

or you want only one Object

Object sendobject = (Object)g.adjMatrix;

adjmatix is 2d array and member of graph class – Mohsan Naqi Feb 03 '13 at 18:31
@Mohsan Naqi: why do want to store it in an Object reference and not in a reference of its real type? – MrSmith42 Feb 03 '13 at 18:33
i want to divide the matrix and send it on different processors to solve it parallel . Currently MPJ does not support direct pass 2d array – Mohsan Naqi Feb 03 '13 at 18:38
