Hi , i have 2 vectors and both of them have roughly 2000 things
is there a built in function in java that i can get the intersectin of the two vectors (to clear up, intersection is the set containing elements which are in both vectors (WITHOUT REPETITION)) ... i can get that but it will have repetition so for example
if i have vector1 which has "1, 2, 3, 4" and vectoro2 which has "1, 3, 3, 5" the intersection would be " 1, 3"....but i cant seem to get that, i get " 1, 3, 3"...is there a a built in function so i dont have to create another vector and loop it thru and compare every elemne tto other elements inside it??

intersection

public static java.util.Vector intersection(java.util.Vector vectA,
java.util.Vector vectB)This method returns a Vector containing the intersection of the objects contained in vectA and vectB.

This method will always return a new, non-null Vector, even if vectA and/or vectB are null.
