Note to myself: Blank finals must be initialized in the constructor. Ex: class A { private int i; A(int ii) { i = ii; } } public class MainClass { private final int i = 0; // Initialized final private final int j; // Blank final private final A a; // Blank final reference // Blank finals MUST be initialized in the...
