title: Get integer difference between string just like strcmp
body: <p>I just need a function that will, for two given strings, return negative, positive or zero value. In C, <code>strcmp</code> is used:</p>
  
  <pre><code>char* a = "Hello";
  char* b = "Aargh";
  
  strcmp(a, b);  //-1
  strcmp(a, a);  //0
  strcmp(b, a);  //1
  </code></pre>
  
  <p>Does Java have any easy intuitive way to do it, or do I have to use the <code>Comparator</code> interface?</p>
