title: How to account for non-prime numbers 0 and 1 in java?
body: <p>I'm not sure if this is the right place to be asking this, but I've been searching for a solution for this on my own for quite some time, so hopefully I've come to the right place. </p>
  
  <p>When calculating prime numbers, the starting number that each number has to be divisible by is 2 to be a non-prime number. In my java program, I want to include all the non-prime numbers in the range from 0 to a certain number, so how do I include 0 and 1? Should I just have separate if and else-if statements for 0 and 1 that state that they are not prime numbers? I think that maybe 0 and 1 should be included in the java for loop, but I don't know how to go about doing that.      </p>
  
  <pre><code>for (int i = 2; i &lt; num; i++){
          if (num % i == 0){
              System.out.println(i + " is not a prime number. ");
          }
          else{
               System.out.println(i + " is a prime number. ");
          }
  
  }
