Im having trouble with this assignment I do not seem to understand how to send a copy of the print out of my Budget() my teacher also wants us to use the split on "\t" for example s.split("\t")....im not sure how this works as well. Any help at all with this assignment would be greatly appreciated. Here is the assignment below as well as what I have so far.
You will be adding methods to the Budget class you created in Assignment 4. First of all, you will add two new data fields. One will contain the year when these expenses are incurred. This allows us to maintain annual objects for archival (and perhaps tax) purposes. The other field will be the name of the person incurring the expenses. Add necessary accessor and modifier methods.
Create an accessor method called getTotal. It will return the current year’s total expenses for a particular category. The category will be passed as a parameter.
Create a method called load. This method receives the path and name of a file as input. The referenced file will contain expense data. The first line of the file will be the year in which the expenses occurred. The remaining lines have the following format: Month Category Amount. A sample line might be this:
February Food $ 21.89
Create a method to send a copy of the budget report to a file named Personal Expenses yyyy.txt, where yyyy is the four-digit year that these expenses are for. The file will contain output that looks much like that created in Assignment 4, showing the current date, the total expenses in each category, and the total annual expenses. A sample is shown below:
Expenses as of Nov 4, 2011:
Tuition: $3200
Food: $2600
Clothes: $600
Books: $450
Total expenses: $6850
