What I have done...

Create a class called Appliance that includes four instance variables-type, brand, model number, and price. Write the code according to our Java coding standards-a constructor that initializes the four instance variables, a default constructor, a get/set for each variable, and toString. Write a test case, ApplianceTest, that creates two Appliance objects with the following data. washer, Kenmore, 102956, $299.99 stove, GE, 8956, $575.75 Then, ask the user their name and how many washers were purchased and how many stoves were purchased. This will be repeated for an unknown number of customers. (sentinel while loop) Enter blah blah to quit...When finished, print the total of each in the format: Customer: nameofcustomerhere1 X Kenmore washers were purchased for a total of $XXXX X GE stoves were purchased for a total of $XXX.x Customer: nameofcustomerhere2 X Kenmore washers were purchased for a total of $xxx.xx X GE stoves were purchased for a total of Sxxx.xx The grand total is $xxx.xx Use JOptionPane for input and output. There will be only one output dialog box
