title: Java - charAt with multiple answers
body: <p>I'm having some trouble with my code, I am trying to test if a position in a char is equal to an integer. The way I have it setup is like so:</p>
  
  <pre><code>    for(int i = 0; i &lt; str.length(); i++) {
          if(str.charAt(i) == '[1234567890]') {
              System.out.println(str);
          }
      }
  </code></pre>
  
  <p>However I'm getting the error "unclosed character literal" when I try to compile. Does anyone know why I'm getting an error, or can explain a more simple way to do this?</p>
