Print Odd Multiples of 3
I am having trouble on an assignment where I need to print the multiples of 3 between 1 and 100 and are odd, so the outcome would be...
3
9
15
21
...
99
I have coded the following which prints all multiples of 3 from 1  99, but I only want the odd multiples.
Java Code:int multOfThree = 0; for (int i = 1; i < 67; i++) { multOfThree += 3; System.out.println(multOfThree); i++; }
Thank you for your help.

Re: Print Odd Multiples of 3
So you want the numbers 3, 3+6, 3+6+6 ... 3+n*6 for n >= 0 and 3+n*6 < 100? hint: a forloop can do it.
kind regards,

Re: Print Odd Multiples of 3
You could also use the modulus operator.
Java Code:if (x % 2 != 0) { // odd }

That might have been a typo, but (true != true) will always evaluate to be false.

Re: Print Odd Multiples of 3
Oh Jos, you always seem so mean spirited. Your method was certainly easier, and would have worked for his needs, but now he knows how to find out if any number is odd or even.

Re: Print Odd Multiples of 3
I think you're smart enough to know the difference between style and substance ;)
However, I have a thread in advanced java that I need an answer too. If you can help me out, I'll gladly accept the sarcasm that comes with it! :D
