Chapter 16. Collections, Generics and Enumerations

This chapter will be part practical and part theory. First, we will code and use the Apple class and get our apple spawning ready for dinner. Afterward, we will spend a little time getting to know two new Java concepts ArrayList and enumerations (enum for short). These two new topics will give us the extra knowledge we will need to finish the game (mainly the Snake class) in the next chapter. In this chapter we will cover:

  • Add the graphics to the project
  • Code and use the Apple class
  • Java Collections, Generics, and the ArrayList class
  • The enhanced for loop

Let's go ahead with the project.
