Given that b and c refer to instances of wrapper classes, which two statements are true? (Choose two) A. b.equals(b) returns true. B. b.equals(c) returns the same result as b == c. C. b.eqials(c) can return false even if c.equals(b) returns true. D. b.equals(c) throws an exception if b and c are different wrapper types. E. b.equals(c) returns false if the type of wrapper objects being compared are different. Answer: B, C But I belive the right answer is :A,E. Do you follow me ? Thanks !!
hmmm its been awhile since I've played with wrappers... so I wrote a bit of code to test it out... I think A, B and E are correct ?? Try writing some snippets to prove me right or prove me wrong.
Can we justify the above question posted by Peter Carter without knowing the contents for the wrapper objects. I mean as you have shown in ur code snippet Integer i = new Integer(2); ---- how can we get the answers without the contents of the objects, as the above instruction shows 2.
