Asuthosh,
A easy way is to create a batch file that sets up path for all your class files.
Add the following to batch file(say setpath.bat)
SET CLASSPATH=.;%CLASSPATH%;c:\com\xxx\yyy
run this batch file in a dos session and then run your java program

Vijay,
You can do something like this to get the number of digits.
int number = 999;
String s = new Integer(t).toString();
int len = s.length();
System.out.println("The length is " + len);

You can buy one from Addison Wesley site (URL is http://www.awl.com/cseng/javaseries/index.shtml) or from Amazon site. The ISBN for the poster is 0-201-43292-7.
