Initialize final variable within constructor in another method

Question

I have a problem which isn\'t really that big, but still gives me some thought as to how Java constructors and methods are used.

I have a constant representing a rad

Answer 1

How about doing like this?

public MyProblematicClass {
    public final int RADIUS;
    public MyProblematicClass(... variables ...) {
       RADIUS = this.setRadiuswithCriteria(criteria);
}

private int setRadiuswithCriteria(criteria crit) {
if(... crit ...) {
    return n;
}
return 0;
}
