/*
Future Scope / Possible Enhancements to this program:
1. I/P validation can be incorporated with either if-else or with suitable Exception Handling
to ensure the data entered by the user is valid. eg. price/amount can't be negative, gst percent
should be between 0 and 28 %... and so on.
2. Discount/Concession feature on Total Amount can be added, just as we have feature to charge GST.
3. A suitable UI can be designed for the same along with a backend.

Objective:
To create a billing system that manages orders, clients, and credit limits using object-oriented principles, specifically inheritance in Java.
Problem Statement:
You are required to design a Java application for a billing system that tracks orders placed by clients and their respective credit limits. The application must include the following classes:
Class Order:
orderId: Unique identifier for the order.orderNumber: Number associated with the order.location: The location where the order is placed.amount: The total amount of the order.gst: GST applicable on the order.totalAmount: Total amount including GST.calculateTotalAmount(): Calculates the total amount by adding GST to the amount.Class Client:
clientName: Name of the client.clientCity: City where the client is located.clientCreditLimit: Credit limit assigned to the client.totalCredit: Total credit used by the client.updateCredit(): Updates the total credit used by the client.checkCreditLimit(): Checks if the client has exceeded their credit limit.Class CreditLimit:
totalClient: Total number of clients.displayClientDetails(): Displays details of all clients and their current credit status.Main Class:
OrderandClientobjects, calculate the total amount including GST for orders, update the client’s credit usage, and check the credit limit for each client.Input:
Details provided include:
orderId,orderNumber,location,clientName,clientCity,clientCreditLimit,amount,gst,totalAmount,totalCredit, andtotalClient.Output:
A summary displaying each client’s details, total amount of orders, GST applied, total credit used, and whether the credit limit is exceeded.
Example Output:
