2.9 Wrap-Up

In this chapter, you learned many important features of Java, including displaying data on the screen in a Command Prompt, inputting data from the keyboard, performing calculations and making decisions. The applications presented here introduced you to basic programming concepts. As you'll 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'll learn how to implement your own classes and use objects of those classes in applications.
