As Martin said, you need to read the Javadoc:
(http://download.oracle.com/javase/6/docs/api/java/util/Scanner.html)

Java is a relatively small language with a huge standard library.  You
cannot understand the language without knowing the basics of the
library.  The library is described in the Javadocs.  If you have not
done so already, download them from
(http://www.oracle.com/technetwork/java/javase/downloads/index.html#docs)
and install them on your computer.  Your IDE should be able to link to
them and use them to help you.

>Why we use nextLine?
It returns the next line of input as a String.  Since your program
reads a line of input it is the obvious method to use.

Ask the authour of the book you are using.
