## @deftypefnx {Built-in Function} {@var{ret} =} java_invoke (@var{obj}, @var{methodname}, @var{arg1}, @dots{})
## Invoke the method @var{methodname} on the Java object @var{obj} with the
## arguments @var{arg1}, @dots{}  For static methods, @var{obj} can be a
## string representing the fully qualified name of the corresponding class.
## The function returns the result of the method invocation.
##
## When @var{obj} is a regular Java object, structure-like indexing can be
## used as a shortcut syntax.  For instance, the two following statements are
## equivalent
##
## @example
## @group
##   ret = java_invoke (x, "method1", 1.0, "a string")
##   ret = x.method1 (1.0, "a string")
## @end group
## @end example
