Linking constructors

Another very basic problem i fear but i cannot figure it out

simplified:

what i would like is:

Code:

---


class constructor {
    int value1 = 0;
    int value2 = 0;

    constructor (int v1, int v2 ) {
        // test v1 and v2
        this.value1 = v1;
        this.value2 = v2;
    }

    constructor (String string) {
        int v1;
        int v2;
        // convert string to v1, v2
        this (v1,v2);  // THIS DOESN'T WORK
    }
}

---

This doesn't work because this(v1, v2) must be the first statement of
constructor (String string)
But at that time v1 and v2 are not even initialised. let alone filled.

And I also don't want to duplicate the tests from constructor (int v1, int v2 ) to other constructors

But is there an other solution?

solution 1:

Code:

---

constructor1(int v1, int v2) {
  setValues(v1, v2);
}
constructor2(String str) {
  v1, v2 = convert();
  setValues(v1, v2);
}
private setValues() {... }

---

solution 2 (and I'd prefer this one):

Code:

---

class Stuff {
  public static Stuff makeFromString(String str) {
    v1, v2 = convert();
    return new Stuff (v1, v2);
  }
  public Stuff (int v1, int v2) { ... }
}

---

static conversion methods also work, if you really need it to be a constructor. i.e.

Code:

---

private static int convertToV1(String conv){...}
private static int convertToV2(String conv){...}

---

I use this one if I need it as a constructor, but need to call another constructor for whatever reason.

Thanks I think i stick to iLuxa's version 1

I prefer that because version 2 is a bit a hidden constructor
and i think at my level clarity is important...

Question how do i make the post [solved]?
