Summary

In this chapter the authors start working with object-oriented programming in more detail. They use playing cards as the example. You start by creating a Card object and by doing so you learn class variables, immutable variables using the final keyword, the equals and compareTo methods, and creating an array of cards. The chapter then introduces you to several search methods.
