Constructor Detail

Combinations

public Combinations(Object[] inArray,
                    int m)

Create a Combination to enumerate through all subsets of the supplied Object array, selecting m at a time.

Parameters:

inArray - the group to choose from

m - int the number to select in each choice

Method Detail

hasMoreElements

public boolean hasMoreElements()

Returns:

true, unless we have already returned the last combination.

nextElement

public Object nextElement()

Returns:

java.lang.Object, the next combination from the supplied Object array.

Actually, an array of Objects is returned. The declaration must say just Object, because the Combinations class implements Enumeration, which declares that the nextElement() returns a plain Object. Users must cast the returned object to (Object[]).
