Online Utility Bills and Bank
Account Checking System:
Introduction Of The Project:
The project which I have chosen is “Online Utility Bills And BANK Account Checking
System. It is a console code without GUI which shows your account balance,account
type with your CNIC,name and account number. You can procede through your
username and password. It also shows which bill to be payed,how much to be payed
or not to pay/your bill is payed.
STEPS:
• Searching
• Task Distribution
• Libraries
SEARCHING:
First we searched about what things are required to make our project then we were
able to find some features and requirements which were necessary for our project.
LIBRARIES:
• Scanner.util
• Arraylist.util
TOPICS IMPLEMENTED:
• Constuctors
• Enheritance
• Encapsulation
• Polymorphism
• Abstraction
MAKING OF Project:
I have taken help from internet as well as YouTube.
HOW DOES IT WORKS ?
• The computer programming language which Iam using in our project is JAVA. It
is the best and easily understandable language and is very user friendly. • If you
enter your CNIC and username along with your password, you will be able to
login successfully.
• Then it will ask you that what you want? Either you want to check your
account balance or you want to know the payed bill.
• Then you can press 1 or 2 to know what you want and if you want to exit at
any stage you can press zero.
Conclusion:
This project can be furthur upgraded like by adding filling in it so it can store data for
the future and I can also make GUI but I haven’t learnt it so I was unable to manage
that.
