title: Need to sum digits in random numbers from loop
body: <p>I'm randomly generating 3 digit numbers using java.util.Random(). The number of random 3-digit numbers that the system prints is controlled by user input. Here's the code:</p>
  
  <pre><code>//If/then statement for determining game type (determines 3 digit numbers)
  if (gameType == 3) 
  
  //for loop to generate random numbers (numGames is how many 3 digit numbers     to print)
  for (int i = 1; i &lt;=numGames; i = i + 1){
  
  int ranNums = randomGenerator.nextInt((999 - 100) + 1) + 100; 
  
  //Print random numbers to user
  System.out.println(ranNums);
  
  sumNums = ranNums % 10;
  </code></pre>
  
  <p>Basically, I want the code to add the DIGITS that are printed from the random number generator. For example, if the ranNums output is 111 and 111, I want the variable sumNums to equal 6, not 222. With the code I have now, it only adds the last digit of each number, (in this case 1 + 1 = 2).</p>
