title: Java name for getter that returns Boolean class according to naming convention
body: <p>I've noticed that for getters that return <code>Boolean</code> (not <code>boolean</code>!) netbeans generates getter with "get" prefix. For example:</p>
  
  <pre><code>private Boolean main;
  
  public Boolean getMain(){
    return this.main;
  }
  </code></pre>
  
  <p>Is this wrong (according to naming convention)? Or "is" prefix only for primitive type?</p>
