title: Eclipse Java - invalid package name - Reserved words in package name
body: <p>I am in the middle of an android project and was trying to create a new package in it.</p>
  
  <pre><code>com.mycompany.myprojectname.new
  </code></pre>
  
  <p>Well, Eclipse is not letting me to create it and is showing this error:</p>
  
  <blockquote>
    <p>Invalid package name. 'new' is not a valid Java identifier</p>
  </blockquote>
  
  <p>I never knew package name has reserved words, which we cannot use. My questions are;</p>
  
  <ol>
  <li>Is this an Eclipse thing? or a Java thing? I tried a pure Java project
  (not Android), just to check, but there also I got the same error.</li>
  <li>What are other reserved words that is not allowed?</li>
  <li>Is there any documentation about this?</li>
  </ol>
