Urgently Write Some Java Code for Small Features of a Project

We have a small application with 2 cards of a sprint we are in the middle off that need to be completed by today. We need this done urgently. Within 12 hours. The instructions are attached in text files. It's a very small task with less than 50 lines of Java code needing to be written to solve it and a couple of JUnit tests. The 2 cards are in text files with some helpful notes on which files to add code to and where they are and the dummy data is.
