Answer 1

You don't add the first value to sum. Just throw it away. Don't save it to a variable. It is just the number of inputs that will follow. That's why I said to re-read the code coach and see what the inputs are.

Answer 2

Move this line outside of and just after while loop.
System.out.print(sum);

Answer 3

You're adding the first input as if it is part of the list. Re-read the challenge and pay attention to what the inputs are. Handle the first input correctly and you should have it solved.

Answer 4

You just need to get the first input before the while loop and dispose of it as your while loop already takes care of the rest.
Add
sc.nextInt();
Before the loop. It doesn't need to be stored into an int, and it should pass all test cases.

Answer 5

I am so Stupid.I should have readed what inputs are properly.I was frustated for So long for nonsense.
Thank you for your help.You are very helpful.I had just now followed you.

Answer 6

It still fails to satisfy case 4 and case 5 of That' odd in Code Coach.

Answer 7

Please tell briefly what i need to change in the code as it is already only adding even integers.And How can i Change it.

Answer 8

If I gets the first input before the while loop and classifies it as even or odd out of while loop.And Then adds it to the sum.It still shows that case 4 and case 5 are wrong
Please Help!

Answer 9

You didn't declare Variable i and so the compiler doesn't know what it is.
It's that simple

Solution:- Just initialise variable i like this.
int i= 9 /* the value can be changed to whatever integer you choose */
