A shopping center offers discounts to its customers based on the table given below. Write a Java class to compute the bill for the shopping center.

Data Members / Instance Variables:

• String n — To store the name of the customer
• char g — To store the gender of the customer. 'M' for male and 'F' for female.
• double amt — To store the amount of purchase
• double dis — To store the discount amount
• double bill — To store the bill payable by the customer

Member Functions:

• Default constructor to initialise data members
• input() — Function that accepts name, gender and amount purchased
• calc() — Function that computes the discount (as per table given below) and bill amount
• display() — Function that displays the data members
• main() — Function that creates an object of the class and calls the member functions.

Calculation of discount is as per the below table:

Amount	Discount
Upto ₹1000	No Discount
₹1001 to ₹5000	2% if Male & 5% if Female
₹5001 to ₹10000	5% if Male & 7% if Female
Above ₹10000	7% if Male & 10% if Female
