tagCloud.addTagClickListener( new TagClickListener() {
  @Override
  public void tagClicked( WeightedWordInterface weightedWord ) {
    doTagClicked( weightedWord );
  }
} );

public void doTagClicked( WeightedWordInterface weightedWord ) {
  System.out.println( String.format( "The word: %s was clicked",
