Checking Multiples from arguments?

I have just started learning Java and I recently got a homework question which I'm unsure of how to do.

Firstly, I have to grab a number from the argument.

Then I check if its a multiple of 5 (0 is counted as a multiple of 5).

IF a multiple of 5, I type "it is a multiple of 5"

IF not, I type "it is not a multiple of "5".

Code:

`public class Exercise1 {`

public static void main(String[] args) {

int numToCheck = Integer.parseInt(args[0]);

for (int multiple = 0; multiple = Math.pow(numToCheck, 5); multiple++) {

System.out.println(numToCheck + " is a multiple of 5");

return;

}

System.out.println(numToCheck + " is not a multiple of 5");

}

}

So far I have this. When I try to run it in Eclipse, I get the error "Type mismatch: cannot convert from double to boolean."

Can anyone help me?

Re: Checking Multiples from arguments?

Have a look at the % operator (modulo operator); if a number n is a multiple of 5, then n%5 == 0.

kind regards,
