21 Aug According to the Code Quality Guide, the program should have a class comment that describes what your program is doing at the beginning.

(SD) Right now, main is not a concise summary of your program. Some of the contents in totalPart() should be in main instead. For example, getting the returns of the income total and expense totals is something that would make more sense for main to have, since its an important part of the program.

(DR) Remember to comment on the return of any non-void method! This lets the reader understand what information they will receive from the method. See the Method Comments section of the Code Quality Guide for a couple examples of how to do this!

(SD) Notice how the code to compute the income/expense totals is almost exactly the same in your totalIncome() and totalExpense() methods! You could eliminate this redundancy by putting this code in a method with a String parameter for the “income” vs. “expense” cases, and calling it twice. See the Election program from lecture for an example of how to do this (make sure you are looking at the ElectionGood.java tab)!

(DR) We use indentation to show the reader the structure of our code. The indentation of a program should increase by one tab every time a curly brace “{“ is opened and decrease by one tab every time a curly brace “}” is closed. The Indenter Tool can help with this!

(UOLF) Notice how lines 83 and 88 are both the same. This means that they should not be in this nested conditional and should be factored before it instead.
