Question

I’m trying to write a program that prints all numbers from 0 to 1,000 where the number mod 5 = 3. This is what I have so far

public class NewMain {
public static void modNumbers(int i)
{

}

public static void main(String[] args) {

    for(int i = 0; i > 1000; i++)
    {
        if(i%5 = 3)
        {
        System.out.println(i);
        }
    }

 }
}

I’m not getting any output, so I know I’m doing something wrong. Should I have a return type in the method?

Change it from:

for (int i = 0; i > 1000; i++)

to

for (int i = 0; i < 1000; i++)

Essentially, the loop never begins because the loop invariant is false (as i is less than 1000), and your print statement is never reached because the loop never initializes.

Additionally, as WTP mentioned, use == for numeric comparisons (an important note is that you use string1.equals(string2) or compareTo with Strings, just for your future reference).
