what you think about firewall

network security you have created a cool discussion.. in your discussion you have taken a good issue..

yes u r rite.... it is a network security.... basically used for filtering the packets comming from the internet........... prog. u wanted.............. /* to find out greater from a and b */ class greater { public static void main(String args[]) { int a = 20, b = 35 ; if (ab) { System.out.println("A IS GREATER THAN B"); } else System.out.println("B IS GREATER THAN A"); } }

Isn't that a firewalls basic job? Haven't been completely sure on what it does.
