Project: Attempt 1

Review of the chapter

In this chapter, we’ve covered the following:

• The built-in methods in Java let us carry out useful tasks.

• The print() and println() methods display data on the screen—numbers as well as text strings.

• Data can be saved in case-sensitive variables.

• The + operator lets us add numbers and join text strings. (There’s an extra space after the operator.)

• The scan.nextLine() method from the Scanner class can take input from the user’s keyboard when our code runs.

With these new skills at our disposal, let’s try to determine how many requirements of the final product we can meet.

This cheat sheet will help us take a quick look at useful commands while we write the code for the final product.
