java.util.Scanner allows you to access the Scanner class contained within the java.util package. This class and methods can allow you to, among other things, gather keyboard input or read a file.

For instance:

Scanner in = new Scanner(System.in);
String input = in.next();

Oracle's Scanning tutorial has more information on the topic.

The import statement is a way of telling the compiler where to look for class definitions when the class is in a package. It saves you from having to code the full package name when you use a class.
Without the import java.util.Scanner; statement, you would have to code
java.util.Scanner in = new java.util.Scanner(System.in);

For this case maybe it doesn't save much, but if you use the Scanner class many times it can save a lot of typing and make the code a little less cluttered looking.


Note: The class name is Scanner not scanner. Case is important
