## @deftypefn {Function File} {@var{val} =} java_get (@var{obj}, @var{name})
## Get the value of the field @var{name} of the Java object @var{obj}.
##
## For static fields, @var{obj} can be a string representing the fully
## qualified name of the corresponding 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_get (x, "field1")
##   x.field1
## @end group
## @end example
##
## @seealso{java_set, javaMethod, javaObject}
## @end deftypefn
