Need to get the min&max from array

> I hope it works as the same way as vectors since this is the first time i'll be using it

What are you refering to here? Collections? No, Collections is a utility class, consisting of handy static methods you call directly.

> 1) can i declare its object as two-dimentinal (like the way you can do to a vector)?

I don't understand what you are referring to here. Also, java.util.Vector is one-diemensional, although you can nest it: Vector<Vector><Integer>>.

> 2) if i store all integer types in the collection object, it sould not have any problems getting the min and max, right?

Maybe a demo is in order (I'll do it without generics).

List list = new ArrayList();

list.add(new Integer(5));

list.add(new Integer(-1));

list.add(new Integer(17));

list.add(new Integer(5));

Integer a = (Integer) Collections.max(list);

Integer b = (Integer) Collections.min(list);

That's an array of three vectors. Why insist on calling it "multi-dimensional".

One more thing: most forum members will tell you to move up from the historical Vector class to ArrayList or some other List type.

Vector[][] v = new Vector[3][6];

Yes, informally, that would be called "multi-dimensional", but really it's an array of arrays of Vectors. You have to compare that to languages like VB that really have multi-dimensional arrays. One nice thing about v being an array of arrays is that you can refer to individual rows:

Vector[] rowj = v[j];
