How to print prime numbers?
<p>I am a beginner to java.And i am trying to print 2,3,5,7,11,13,17,19</p>

<p>This is my thought process.the above numbers i want to print are prime numbers which means they can only be divided by themselves or the value 1.So i will need to have a condition which is if(i%i==0 || %1==0){</p>

<pre><code>import java.util.*;
public class PrimePrinter{
    public static void main(String[] args){
        Scanner sc=new Scanner(System.in);
        System.out.print("Enter num&gt; ");
        int input=sc.nextInt();

        for(int i=2;i&lt;=19;i++){
            if(i%i==0&amp;&amp;i%1==0){
                System.out.print(i);
            }else {
                System.out.print(",");
            }
        }
    }
}
</code></pre>

<p>I try to think through my codes but i wonder why it will print out 2,3,4,5...and up till 19 when i already have a condition.I will appreciate if someone will give me hints for me to work out instead of posting the solutions.</p>
