Assignment #6

Exercise (due Tuesday, Nov. 11): 

• In the last lab exercise, you modified your Inventory class to introduce a removePart(int index) method which checked the index, retrieved the part to be removed, retrieved the name of the part to be removed, and then printed a message displaying the part name and asking the user if that was the part to be removed.  You then used the Scanner class to accept a yes or no, and then performed the action indicated (no action if the user did not confirm) printing a message either way.

• Modify the removePart method of the Inventory class again, but this time

• Instead of accepting the number to be removed, use the code from this last example to throw up a dialog box asking for the number (index) of the number to be removed, accepting that number (which will need to be converted from a String to an integer).
• Check that the number returned is in range.  If it is not, put up a warning message and do nothing more.
• If the number is in range, retrieve the part and the part name as before, and throw up a yes/no/cancel dialog box with the name of the part and asking the user whether or not the part should be deleted.
• If the user clicks on NO or CANCEL, do nothing, but throw up a dialog box saying that the part was not deleted.
• If the user clicks on YES, delete the part and throw up a confirming dialog message.
• (added in class Friday) Be sure to include adequate documentation, including
• Header documentation (in JavaDoc format), including @name, @version (a date)
• JavaDoc documentation, including purpose, @param (where appropriate), @returns (where appropriate) for each method. If you have not already done this for your Part and Inventory classes, please do so now.
