simple question

[winged mauve]

Just wondering how I update the instance of this class or whatever it's called. If i make something like this: Area wcArea = new Area(3174, 3235, 3222, 3253); how would I later change the values of wcArea? thanks

Depends on what class Area proposes. Some classes are said immutable: they don't allow to change the values that were set after construction.

if it's not immutable how could you change it

Like I said, it depends on what class Area proposes. In other words, by what mechanism is it not immutable

[hallow oar]

You could do it in a few ways, easiest is just make the variables you are setting public. Such as:

public class Area {
  public int a, b, c, d;
  public Area(int a, int b, int c, int d) {
    this.a = a;
    this.b = b;
    this.c = c;
    this.d = d;
  }
}```

you can then modify them by doing:

Area wcArea = new Area(50, 50, 100, 100);
wcArea.a = 100;
// changing other area boundaries as necessary

You can also use getter or setter functions if you need something more complex or the variables need to be private

Fundamentally, setters are an established expectation in Java, even it it smells like cargo cult

That way you will just set the value in the moment that you create the object, so you should create set methods to be able change the attribute values.
