title: Java, converting string to integers then add all the integers together
body: <p>I need to add 8 numbers together from a string.E.g. If someone enters say 1234 it will add the numbers together  1 + 2 + 3 + 4 = 10 then 1 + 1 = 2. I have done this so far. I cannot figure out how to add these numbers up using a for loop.</p>
  
  <pre><code>String num2;     
  String num3;   
  num2 = (jTextField1.getText());
  num3 = num2.replaceAll("[/:.,-0]", "");
  
  String[] result = num3.split("");
  
  int inte = Integer.parseInt(num3);
  
  for (int i = 0; i &lt; 8; i++){
  
  // Stuck
  
  }
  </code></pre>
