## @deftypefn {} {@var{obj} =} java_set (@var{obj}, @var{name}, @var{val})
## Set the value of the field @var{name} of the Java object @var{obj} to
## @var{val}.
##
## For static fields, @var{obj} can be a string representing the fully
## qualified named of the corresponding Java class.
##
## When @var{obj} is a regular Java object, structure-like indexing can be
## used as a shortcut syntax.  For instance, the following two statements are
## equivalent
##
## @example
## @group
##   java_set (x, "field1", val)
##   x.field1 = val
## @end group
## @end example
##
## @seealso{java_get, javaMethod, javaObject}
## @end deftypefn
