Mock question

[Anonymous]

Hi!
Given the following pairs of method declarations, which of the statments are true?
1.
void perform_work(int time){ }
int perform_work(int time, int speed){ return time*speed ;}

2.
void perform_work(int time){ }
int perform_work(int speed){return speed ;}
3.
void perform_work(int time){ }
void Perform_work(int time){ }
A- The first pair of methods will compile correctly.
B- The second pair of methods will compile correctly.
C- The third pair of methods will compile correctly.
D- The second pair of methods will not comile correctly.
E- The third pair of methods will no compile correctly.
The answer is A and D but I think that the answer is A,D,E because I believe that can not have two identical methods in the same class. And I try compile this but compile error.
Can someone help me?
Thank you in advance.

Hi Jordi ,
You know the answer - Just think CASE SENSITIVE .
Peace

Exactly,
you have two different methods in this case.

This question is very similar to the Review Question 4.10 in Khalid Mughal's book. You may want to take a look at the explanation the authors have given at the back of the book if your questions are still not answered.

Hi,
My curious is what is the problem with C? I think either C or E should be correct. As you said E is not correct, how about C?
Sorry I do not have Khalid Mughal's book, I can not check with that.Thanks for you reply!

Hi,
The answers should be A,C and D.
C is correct because the third pair has two different method names, which implies method names are case-sensitive.

If you guys noticed, the original post says A & D are the correct answer choices whereas the correct answers (for the original post) are what Desai Sandeep suggested (A, C & D). This is because, I believe this quesion has been slightly modified from review question 4.10 of Khalid Mughal's book for which the answers A & D are appropriate.
For the benifit of those who don't have the book...I have posted that question below.

Given the following pairs of method declarations, which of the statments are true?

void fly(int time){ }
int fly(int time, int speed){ return time*speed ;}

void fall(int time){ }
int fall(int distance){return distance ;}

void glide(int time){ }
void Glide(int time){ } 

(a) The first pair of methods will compile correctly and overload the method name fly.
(b) The second pair of methods will compile correctly and overload the method name fall.
(c) The third pair of methods will compile correctly and overload the method name glide.
(d) The second pair of methods will not comile correctly.
(e) The third pair of methods will no compile correctly.

The correct answer choices are choices (a) & (d).
Hope this helps
Shyam
