## @deftypefnx {Function file} {@var{a} =} javaArray (@var{class},@var{M},@var{N},...)
##
## Creates a Java array of size [@var{M},@var{N},...] with elements of
## class @var{class}. @var{class} can be a Java object representing a class
## or a string containing the fully qualified class name.
##
## The generated array is uninitialized, all elements are set to null
## if @var{class} is a reference type, or to a default value (usually 0)
## if @var{class} is a primitive type.
##
## @example
## a = javaArray ("java.lang.String", 2, 2);
## a(1,1) = "Hello";
## @end example
##
## @end deftypefn
function [ ret ] = javaArray (class_name, varargin)
switch length (varargin)
case 0
error ("missing array size");
case 1
dims = varargin{1};
otherwise
dims = [varargin{:}];
endswitch
ret = java_invoke ("org.octave.ClassHelper", "createArray", class_name, dims);
endfunction
