gerceWedy : At a guess this Q is asking if a manual 'system' would be 'more secure' than a computerised one .

The answer is, of course, 'it depends', however, generally, no ..

The weakest link in any system is NOT some external 'super hacker' but the STAFF WHO USE IT .. these are the people who miss-use the system, eg enter incorrect data either by accident or in an attempt to 'bend' or defraud the system or 'leak' data to friends by 'gossiping' .. or sell data to those who are willing to pay ..


A 'manual' system depends 100% of the honesty of the staff using it .. and, because it's totally manual, 'the system' can't 'authenticate' the user (anyone with the key to the records room / cabinet has access .. as does anyone who finds it left unlocked ..)

Further, it's virtually impossible to 'compartmentalise' the data .. i.e. the manual user needs access to all the data in order to use the system ... so Purchasing (those who place orders) have access to the same data as Invoicing (those who pay the bills) and Accounts (those who track the money) = with the result that it's quite possible for one person to raise fake purchase orders, pay themselves and 'doctor' the Accounts to avoid discovery !


A computer system can not only authenticate the user (by insisting on the use of 'RFID cards' etc that are obviously 'fixed to the user' (because they also need them to open doors) so it's not possible to 'leave the system logged in' when moving away from the terminal) but can also control the changes that each user is permitted (as well as keeping records of 'who did what' so any miss-use can be discovered)

A computer system can 'compartmentalise' data so it's not all 'in one place' ... Purchasing can raise orders but have no access to the Invoicing - conversely Invoicing can make payments but have no access to Purchasing .. whilst Accounts can 'look at' everything but change nothing ..

Further a computer system can implement 'checks' .. for example, if a 'key card' is used to access the system after the 'owner' has left for the day (or not arrived, or on holiday, or off sick etc) .. or it could prevent an invoice being paid until the purchased goods have been delivered and 'checked in' using eg a bar-code scanner in Goods in .. and things like detecting 'duplicate orders' (or duplicate invoices / payments) would be 'built in' to the basic code ..

Finally, a computerised system using RFID tags can virtually eliminate 'shrinkage' (the fact that a percentage of all goods in the supply chain 'go missing' between the factory production line and the paying customer) by 'tracking' the goods all the way to the tills (and out of the doors ... whilst sounding an alarm when a RFID tag is 'seen' at any of the exit doors but not recorded as having been paid for at the tills :-) )

operforGowrib : "design and implement an application that reads an integer value representing a year input by the user. the purpose of the program is to determine if the year is a leap year. a year is a leap year if it is divisible by 4, unless it is divisible by 100 but not 400. for example the year 2003 is not a leap year, but 2004 is. the year 1900 is not a leap year because it is divisible by 100, the year 2000 is a leap year because even though it is divisible by 100 it is also divisible by 400, produce an error for any input lower then 1582( the year gregorian calendar was adopted)

lottililrom : Create a new class which has no constructor -

import java.util.Scanner;

public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
System.out.print("Enter a four digit year - ");
int year = sc.nextInt();
boolean isLeap = ((year%4 == 0 ) && (year %100 !=0) || (year % 400 == 0));
System.out.print("You entered " + year);
if (isLeap) System.out.println(" which is a leap year");
else System.out.println(" which is not a leap year");
}
