I have the following homework problem:
Write an application integer on that reads an integer and determines and prints whether it is odd or even.

Is this homework? If so, what have you tried so far?Buhake Sindi– Buhake Sindi2011-04-03 13:37:58 +00:00Commented Apr 3, 2011 at 13:37

It's a homework, isn't it? And maybe you should show what you've done so far.RollingBoy– RollingBoy2011-04-03 13:39:13 +00:00Commented Apr 3, 2011 at 13:39

This sounds like a homework question, and probably should be tagged as such. As a rule, the community gives hints on homework questions only when you've shown sufficient effort to attempt to solve the problem first.Charlie– Charlie2011-04-03 13:39:25 +00:00Commented Apr 3, 2011 at 13:39

Use the Scanner class for reading input.
Store that input into an integer. Check if input is really a valid integer. Otherwise, throw an exception.
Afterwards, use the modulo operator to check if it's odd or even.
Use System.out.println to print if it's odd or even.

@The Elite Gentleman: I didn't really solve it; I just gave a description of what to do. OP must gather the pieces to solve the puzzle. Writing the actual code would be solving his homework.

+1. @Elite I think @darioo answered exactly the way one should, concerning homework questions.
public static void main(String[] args) {
System.out.println("Enter number");
Scanner sc = new Scanner(System.in);
try {
int i = sc.nextInt();
if (Math.abs(i) / i == 1) {
if ((Math.abs(i) % 2) == 0) {
System.out.println("Even");
} else {
System.out.println("Odd");
}
}
} catch (Exception ex) {
System.out.println("Exception " + ex.toString());
}
}
