IN JAVA

Write a program that uses the following Purchase class to set the following prices:

Oranges: 10 for 2.99

Eggs: 12 for 1.69

Apples: 3 for 1.00

Watermelons: 4.39 each

Bagels: 6 for 3.50

Then calculate the cost of each of the following five items and the total bill:

2 dozen oranges

2 dozen eggs

20 apples

2 watermelons

1 dozen bagels.
