Java™ How to Program, Seventh Edition

2.10. Wrap-Up

You learned many important features of Java in this chapter, including displaying data on the screen in a Command Prompt, inputting data from the keyboard, performing calculations and making decisions. The applications presented here were meant to introduce you to basic programming concepts. As you will see in Chapter 3, Java applications typically contain just a few lines of code in method main—these statements normally create the objects that perform the work of the application. In Chapter 3, you will learn how to implement your own classes and use objects of those classes in applications.
