how do i access data structure in different class

[vin0_oce]

Hi , Please help me, i've created a datastructure in class Pos, which is used in class ass1.

the Pos type is changed to ass1 type in ass1 class
with the function ass1()

so then i have a "ass1 array[][]"
now, i am having problem accessing the Pos individual elements in this array ..
can't really do system.out.print(array[1][1].value);

how do i access them ?

Firstly, I suggest you choose new names for your classes - I got utterly confused when reading your instructions. Also, it is the Java convention to capitalise the first character of a class name.

Secondly, you access the elements of an array thus:

  ...
  int [][] circuit_board = new int[11][11];
  System.out.println(circuit_board[1][2]);
  ...
