title: Check if a string has all the characters of another string
body: <pre class="lang-java prettyprint-override"><code>String one = "This is a test";
  String two = "This is a simple test";
  </code></pre>
  
  <p>I want to check if <code>two</code> contains all the characters that are in <code>one</code>, and ignore the fact it has extra characters.</p>
