It sounds as though you didn't download and install the Java SE 
documentation package. You need it: the Java equivalent of the C standard 
library is considerably bigger and is fully documented there via the 
Javadocs documentation tool, which is also part of the standard JDK. 
C/C++ doesn't have a standard documentation tool that comes near 
Javadocs. 

The Java 6 standard class library includes the Scanner class, so of 
course it is fully described in the Java 6 documentation set. The 
description there is much better than any summary we might write. Quite 
apart from anything else, you'll find that writing your comparison is a 
lot easier if you have the documentation set installed and use it to help 
your writing.
