Using Scanner object versus creating own System.in class methods

[theundergod]

I am learning Java on my own at the moment and the author of the book I am using created his own class with input methods. He uses methods all based around a method called getChar() which calls the System.in.read() method. All other methods he created like the getInt() and getWord() call on the getChar()method and handle the characters appropriately to get the desired Int or String. Is there a benefit to defining your own like this rather than just using a Scanner object in each of your own defined input methods? I am wondering if he did this just illustrate how Java handled input to the students. Thanks for any info.

a) It might be to illustrate something to students...
b) It might be a rather old book. Scanner is one of the youngest girls in town (since 1.5, as you may see in the javadocs).
