This chapter was all about flow control: How to conditionally execute sections of code, and how to execute sections of code multiple times. This chapter discusses the if and if-then-else statements for general conditional statements, and the switch statement for a specific variety of conditional statements. Iterative statements were discussed in the form of while, do while, and for statements.
Now Java is more than just a glorified calculator, you now have the ability to programmatically make decisions and do some real computations.
The next chapter will take what you have learned thus far to the next level and enable you to create reusable methods that perform specific sets of functionality.
