title: simple java regular expression not working
body: <p>I have this simple example of a regular expression. But it is not working. I don't know what I am doing wrong:</p>
  
  <pre><code>String name = "abc";
  System.out.println(name.matches("[a-zA-Z]"));
  </code></pre>
  
  <p>it returns false, it should be true. </p>
