title: Is there any Java library to parse a simple grammar?
body: <p>I want to use Java to parse a very simple grammar, for example:</p>
  
  <pre><code>/*comments*/
  "aaa" = "bbb"
  </code></pre>
  
  <p>That's all. I want all tokens (comment, string, equals).</p>
  
  <p>Is there any Java library that can handle this?</p>
