For the following exercises, use the incremental development methodology to implement the program. For each exercise, identify the program tasks, create a design document with class descriptions, and draw the program diagram. Map out the development steps at the start. Present any design alternatives and justify your selection. Be sure to perform adequate testing at the end of each development step.

Redo Exercise 26 on page 143, but this time define and use programmerdefined classes.

Reference Exercise 26 on page 143:

For the following exercises, use the incremental development methodology to implement the program. For each exercise, identify the program tasks, create a design document with class descriptions, and draw the program diagram. Map out the development steps at the start. State any assumptions you must make about the input. Present any design alternatives and justify your selection. Be sure to perform adequate testing at the end of each development step.

Repeat Exercise 25, but this time, accept the date when the order is placed and display the expected date of arrival. The expected date of arrival is two weeks (14 days) from the date of order. The order date is entered as a single string in the MM/dd/yyyy format. For example, November 1, 2004 is entered as 11/01/2004. There will be exactly two digits each for the month and day and four digits for the year. Display the output in the following format:

Reference Exercixe 25:MyJava Coffee Outlet runs a catalog business. It sells only one type of coffee beans, harvested exclusively in the remote area of Irian Jaya. The company sells the coffee in 2-lb bags only, and the price of a single 2-lb bag is $5.50. When a customer places an order, the company ships the order in boxes. The boxes come in three sizes: the large box holds 20 bags of 2 lb, the medium 10 bags, and the small 5 bags. The cost of a large box is $1.80; a medium box, $1.00; and a small box, $0.60. The order is shipped using the least number of boxes. For example, the order of 52 bags will be shipped in two boxes, one large and one small. Develop an application that computes the total cost of an order. Display the output in the following format:
