server ,you can download from java.sun.com
, It worked well under winXP

Color[] c2 = {new Color(255,0,0),new Color(255,255,255),new Color(0,0,255)};
you should use constructor
Color(int ,int,int)

String [] s=args[] //it's wrong~~
String [] s=arg; //that didnt copy Array arg to
s
i prefer to use a loop to copy element from one
array to another

StringBuffer is not a consistant container~~
the length of the StringBuffer can change
after it was initialized..
i guess java compiler prevent you doing such
comparing

i agree with your friend.
only method overriding comes under polymorphism
you can use one kind of object perform differrent
Action by invoking same Function!!!
so that must be OVERRIDE!

in your example :
101%n=2
so 101=q*n+2 we have q*n=99
so n is the factor of 99
implementation :
for(int i=1;i<=99;i++)
if((99/i)==0){
n=i;
System.out.println("n is : "+n);
}
}
