Re: Creating dynamic double dimensional arrays.

  You can even create an array at run time whose
  /number of dimensions/ is only determined at
  run time. For example: 4 ' 5 ' 6 (i.e., three
  dimensions):

public class Main
{
  public static int[] cdr( final int[] list )
  { return java.util.Arrays.copyOfRange( list, 1, list.length ); }

  public static java.lang.Object build( final int ... extensions )
  { final java.lang.Object array = java.lang.reflect.Array.newInstance
    ( java.lang.Integer.TYPE, extensions );
    for( int i = 0; i < extensions[ 0 ]; ++i )if( extensions.length > 1 )
    java.lang.reflect.Array.set( array, i, build( cdr( extensions )));
    else java.lang.reflect.Array.setInt(( int[] )array, i, i );
    return array; }

  public static void print( final java.lang.Object array )
  { for( int i = 0; i < java.lang.reflect.Array.getLength( array ); ++i )
    if( array.getClass().getName().startsWith( "[[" ))
    print( java.lang.reflect.Array.get( array, i )); else
    java.lang.System.out.print( java.lang.reflect.Array.getInt( array, i )); }
    
  public static void main( final java.lang.String[] args )
  { print( build( 4, 5, 6 )); }}
