  Tutorial: Console Input: Scanner

The java.util.Scanner class (added in Java 5) allows simple console and file input.

Tutorial Details:

The java.util.Scanner class (added in Java 5) allows simple console and file input. Of course, your program should eventually have a GUI user interface, but Scanner is very useful for reading data files.

Notes
Altho we only need the Scanner class from the java.util package, the most common programming style is to make all classes (*) visible.
Closing the console isn't really necessary, but it's a good habit. If we had been reading a file, which is common with Scanner, closing it would be important.
