You wil need this line on the top of your code in order to compile: import java.util.Scanner; This kind of import statement is very important. They tell the compile of which kind of Scanner you are about to use, because the Scanner here is undefined by anyone. After a import statement, you can use the class Scanner directly and the compiler will know about it. Also, you can do this without using the import statement, although I don't recommend: java.util.Scanner scanner

Looks like you are missing an import for the Scanner class. –bmargulies Apr 27 '13 at 1:08 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote accepted You need to import the Scanner before you use it: Scanner keyboard = new Scanner(System.in); Also I do not know if you forgot to paste it, but you also have to give a name to your class.
