Methods

public classSum {private intval;Sum(intv) { val = v; }Sum() {this(0); }void inc(inti) {val += i; }void inc(Sum s) {val += s.val; }public static void main(String[] args) {Sumsq = new Sum();SumsumSq = new Sum(); for (inti = 0; i < 4; i++) {sq.inc((2 * i) + 1);sumSq.inc(sq);System.out.println(sq.val); }System.out.println(sumSq.val);}

}

Methods

public classSumTwoextends Sum {SumTwo(intv) { super(v); }void inc(inti, intj) {inc(i+ j); }public static void main(String[] args) {SumnotFib = new SumTwo(0);intfst = 0;intsnd = 1; for (inti = 0; i < 4; i++) {notFib.inc(fst, snd);inttmp = fst + snd;fst = snd;snd = tmp; }System.out.println(notFib.val);}

}
