Annotations are a overly complex, unclear part of Java (these words is not for those people who learn by heart in whole parts of the text without dissection). This complexity makes the annotation part of Java is overly unpleasant in learning. The conditions of this challenge are good: 1) simple and clear explanation in beginning, 2) most of the program written (this is good: more tutoring and less suffering). But I have been some suffering from uncertainty of the conditions in the values of budgetLimit too, chrynan: this is a good subchallenge, but lacks a little clarification: "I offer to guess about the values for budgetLimit from the problem statement."
