Now we will continue with our running example, the search engine. What we want to do here is to try to predict whether a URL comes from the first page of the search engine results or not. So, it is time to use the material we have covered so far in this chapter.
In Chapter 2, Data Processing Toolbox, we created the following object to store the information about pages:

private int position;
private int page;
private int titleLength;
