Is there in Mathematica something like class in Java or struct in C?

Question

I am new to Mathematica and I am very impressed with its features. Although I don't understand how to do a simple thing: for example, I want to create few point variables (say a,b,c,d,e), each storing its x and y coordinates. In Java, I would write something like this:

class Point {
    float x;
    float y;

}
...
Point a;
a.x = 2,5;
a.y = 1,2;

How do I do same thing in Mathematica? Thank you!

Just define n-dimensional points/vectors as length n lists; e.g. a = {2.5, 1.2}. — J. M.'s missing motivation, Sep 17 '17 at 11:00
Mathematica is not object-oriented. I suggest you go through a few tutorials and see how things are usually done the Mathematica way. What you know from Java or C should not be your starting point when learning Mathematica. — Szabolcs, Sep 17 '17 at 11:02
Look up Part[] and Extract[] in the documentation. Try e.g. a[[1]] . — J. M.'s missing motivation, Sep 17 '17 at 11:03
"How do I access elements?" By reading the documentation. A minimal level of Mathematica knowledge is expected before you ask questions here. I am not being snarky. JM's answer is technically accurate, but you would not usually work this way with a 2D vector most of the time. — Szabolcs, Sep 17 '17 at 11:03
Welcome to Mma.SE! Your question may be put on-hold as it seems to be off-topic, i.e it arises from simply not reading the documentation, at all, and is unlikely to help any future visitors. Don't be discouraged by that cleaning-up policy. Your future good questions are welcome. Learn about common pitfalls here.
