public class Tuple

extends java.util.ArrayList

In languages, a data object containing two or more components. Also known as a product type or pair, triple, quad, etc. Tuples of different sizes have different types, in contrast to lists where the type is independent of the length. The components of a tuple may be of different types whereas all elements of a list have the same type. Examples of tuples - in standard notation - are <1,2>, <"Tuple",True>, ,z>. The degenerate tuple with zero components, written <>, is known as the unit type since it has only one possible value which is also written <>.
