There is really no direct support for two dimensional arrays in Java. What you are really dealing with is an array of arrays.

So to write the whole thing to a file, just iterate through the outside array and each of the contained arrays in order.

You didn't specify what kind of array it is. Is it an array of
primative types, or object? In either case, you can use a DataOutputStream ans just iterate through the tow arrays:

for( int i= 0; i < array.length; i++ )
      for( int j = 0; j < array[i].length; j++ )
            ostream.writeInt( array[i][j] );
