Predict the Box Comparison
CHALLENGE
Difficulty: intermediate+25 XP
Without running code first, predict each result, then implement
Solution.answers() returning them as a boolean[]:
1. Integer a = 1000, b = 1000; a == b โ ?
2. Integer c = 100, d = 100; c == d โ ?
3. Integer e = 1000, f = 1000; e.equals(f) โ ?
4. int g = 1000; Integer h = 1000; g == h โ ? (unboxing comparison)
Index 0..3 in the returned array. Then read the explanation the tests give
you and reconcile it with your intuition.
