Payed by the number of coded lines?

switch (userChoice) {
case 1:
  ((VO) vo).setAne(new Integer(1));
  break;
case 2:
  ((VO) vo).setAne(new Integer(2));
  break;
case 3:
  ((VO) vo).setAne(new Integer(3));
  break;
default:
  break;
}

Abstract methods? what is that?

protected void initialize() {
    // do nothing here, it will be overridden in the subclasses
}

You can never be sure

if (true) {
    // ...
}

We need to go deeper

String infoMessage = getInfoMessage();
screenInfoMessage = new String(infoMessage);
// ...
infoMessage = new String(screenInfoMessage);

When in doubt, use a switch

switch (type) {
default:
    compositeFactory = new EditorCompositeFactoryImpl(parent, type);
    break;
}

One if statement is not enough

if (compositeMode == DialogMode.UPDATE_MODE) {
    hierarchyTabCompositeFactory.setFamily(false);
}
headTabCompositeFactory.bind();
if (compositeMode == DialogMode.UPDATE_MODE) {
    hierarchyTabCompositeFactory.setFamily(true);
}
if (compositeMode == DialogMode.UPDATE_MODE) {
    hierarchyTabCompositeFactory.bind();
}

If not statement

if (article instanceof Article
    && ((Article) article).getArticleCode() == null) {
    // NOTHING
} else {
    setEnableTitle();
}
