This discussion board I will discuss what predefined methods that I might consider using and why. Also, where to find other sources for finding predefined Java classes and methods. Last we can look at some other programmer defined methods I might consider using based on the class and case diagrams from week 1.

Well the first method I will definitely use is the JOptionPane method. This is the perfect tool for allowing the customer to enter the required data for ordering golf balls from SkyGolf. This will allow them to be able to select the different options for the balls, color, number, and type in the required information for a custom imprint or adding a logo. JOptionPane can then also display in a window after all of the selections have been made and the customer can verify the information is correct. Then you can prompt the customer if everything is correct to enter a 1 or if it is incorrect then maybe select a 2 to route them back to the selection process. The scanner method can also be used to accomplish the same results except all of the information is shown line by line in a command window. I would use this method for the customer input but the JOptionPane has a better visual appearance for the user with graphical user interface (GUI).

I have found that the Oracle website is a good source for finding predefined Java classes and methods. These can be found at the address http://docs.oracle.com/javase/6/docs/api/allclasses-noframe.html. It’s really unbelievable how of these are available. Also, just by using the program will give the experience using the predefined classes and methods to be able to build your own programmer defined methods.

Well it seems there is going to be many choices for creating programmer defined methods for my class and case diagrams for SkygGolf. I would definitely use value returning methods so the customer can not only see their selections and they can be assigned to a variable. Of course we will need the getFirstName() and the getLastName() methods to gather customer information. The getPrice() would be a method I would create to be able to show the customer the price of the golf plus being able to show the total price for the order to include calculating the sales tax. A double variable defined will hold the result of the method. The getEmail() would be another method I would create so the customer could have ordering information sent to them electronically and future emails for new product information.

In conclusion, I look forward to working more with the GUIs like JOptionPane and other applications when building programs in Java. I found a lot of helpful information on the Oracle website which I would expect to use in the future for reference. I’m sure with more practice creating methods will come a lot easier then what I understand now. It seems that the initial planning using case and class diagrams will be very helpful when building programmer defined methods.
