Cystom class in an array?

I was wondering if it was possible to put a custom class in an array. So that way you could do like:

Code:

---

//something.java
class something {
boolean visible;
int x,y;
}

//blah.java
//...
something[4].x = 40;
something[4].y = 30;
something[4].visible = true;
//...

---

yes it's possible

Would be better practice however to work more OO. Create methods and private variables to abstract actually changing private data explicitly when working outside the class.
