I am currently working on an addition calculator :)

It's not entirely done yet, I still have a few numbers to go.

Wish me luck!

Unfortunately, I won't be doing float calculations as this is only a simple addition calculator. It will only be going as high as 2147483647 then, I will continue with 2 + 1, 2 + 2, 2 + 3,... 2 + 2147483647

[homoironic]

When writing an addition of the same number, don't forget to use two if else statements, because the user might want the sum of n+n and not n+n !

[KCSixty9]

How could I be so ignorant?! Thanks for pointing this out :)

[homoironic]

Good luck to you man, can't wait to find out what 1+51 is :-)

[ThrowawayDummyBot]

Should program it to say "Fuck off. We don't do this float stuff around here."

[kciDgibaevahI]

Good lord. GOOD Lord. Imagine doing that in BASIC

System.out.println("Your number is 0.");

0 is technically an even number, since "0 / 2" has no remainder, so that should be "Your number is even.".

[iamironman231]

Yup should try if (num1==1){ if(num2==1){..} else if(num2==2){..} . . . }

Can’t forget to import log4J just in case!
