Write a program using user-defined methods. Write the following methods:
1. getPrice() which asks the user to input the original price of an item.
2. getDiscount() which asks the user to input the discount rate. The method
should return the decimal version of the rate. For example, if the user inputs 25% for
the discount rate, the value returned by getDiscount() would be 0.25
3. calculateDiscount() which returns the amount of discount based on the user’s
input. Parameters for this method would be the original price and the discount rate.
4. calculateSalePrice() which returns the sale price using parameters of original
price and amount of discount.
5. output() method – format the output in the following manner:
Original Price: $200
Discount Rate: 20% (decimal here is not acceptable)
Amount of Discount: $40
Sale Price: $160
Use the following variables and main method()
public static void main (String [] args)
{
double original, rate, discount, salePrice;
original = getPrice();
rate = getDiscount();
discount = caclulateDiscount(original, rate);
salePrice = caclulateSalePrice(original, discount);
output(original, rate, discount, salePrice);
}
Write your methods using these names and handling these arguments for the
parameters of each method. Do not change this main method. Save the program as
Cheaper.java.
