title: How to check if a string is only numbers without a try/catch?
body: <p>I need to check if a string has only numbers in it so that I can parse it to an int. I am not allowed to use a try/catch statement. Nothing I have tried through here has worked thusfar, that's why it may seem like this has already been asked. Here's what I am trying:</p>
  
  <pre><code>    if (team1Part2.equals(Integer.parseInt(team1Part2))) {
          team1Score = Integer.parseInt(team1Part2);
      } else {
          team1Score = sc.nextInt();
      }
  </code></pre>
  
  <p>It's being read from a file, and if the first input isn't an integer, the next one is, but when ran, I get a mismatch on the else statement for some reason.</p>
