title: While loop numbers sum
body: <p>I need help on how to calculate sum of the numbers that while loop prints. I have to get numbers 1 to 100 using while loop and calculate all those together. Like 1+2+3...+98+99+100. I can get numbers but can't calculate them together. Here's my code: </p>
  
  <pre><code>public class Loops {
      public static void main(String[] args) throws Exception {
          int i = 1;
          while (i &lt; 101) {
             System.out.print(i);
             i = i + 1;
          }
      }
  }
  </code></pre>
  
  <p>How do I make it only print the last sum? If I try to trick the equation it just hangs.</p>
