Unique in Java?

[abraxas334]

Simple problem really:
I have a Vector definied like this:
Vector<int []> v;

now the int array passed is always of length 2 so I end up with vectors looking like this:
0 15
0 15
12 18
15 12
15 12
15 12
18 19
18 19
19 21
19 21
19 21

I just want all single occurances of each set of numbers. In C++ I 'd just sort my 2-d vector and then use unique on it. Is there an equivalent in java?
I guess it is already sorted in this case, but how do I get rid of the duplicates?
Thanks,

You could use a hash set. http://download.oracle.com/javase/6/docs/api/java/util/HashSet.html

This will only contain unique entries.

Use a set. It will take care of that for you.
