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.

Code:

---

      int multOfThree = 0;
      for (int i = 1; i < 67; i++)
      {
        multOfThree += 3;
     
        System.out.println(multOfThree);
        i++;
     
      }

Thank you for your help.

So you want the numbers 3, 3+6, 3+6+6 ... 3+n*6 for n >= 0 and 3+n*6 < 100? hint: a for-loop can do it.

kind regards,

You could also use the modulus operator.

Code:

---

if (x % 2 != 0)
{
  // odd
}

AHh I see now. multOfThree%2 produces the pattern I want for printing every other line (0,1,0,1,0), so, by making an if statement (true != true), it will print in that order.

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

Sure, why implement an efficient solution while you can hack something together?

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.

What is "mean spirited" about efficiency?

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

If it's the thread about rendering cells in a JTable, I thought Fubarable answered in in his reply #5.
