That was a bit of a hefty chapter, but we learned lots of new techniques such as storing and manipulating with arrays, creating and using sound effects, and saving important data such as a high score, in our game. We also took a very brief look at the powerful but simple-to-use Animation class.

In the next chapter, we will be taking a more theoretical approach, but we will have plenty of working samples too. We will finally be opening the black box of Java classes so that we can gain an understanding of what is going on when we declare and use objects of a class.
