9,603 PointsWhich part are you having an issue with?
CreditorTest.java contains some junit tests, which test code so that if you continue working on Creditor.java, and the test breaks you know where and how (or a general idea on how) to fix it.
and Creditor.java is the code you are working on.
It is all a part of Test Driven Development, which you can find more info on TT or here: https://en.wikipedia.org/wiki/Test-driven_development
