Java data processing needs to be fixed

I hired someone on freelancer recently to create some java classes that would process data from a database. The data is timestamp/temperature readings values and air conditioning on/off/timestamp values. From this it is to calculate the average rate that the temperature fell during the time period along with how long the air conditioner was on how long it was off and some other calculated values from the data. The problem is the freelancer wouldn't let me test the code without paying him. Once I paid him the code didn't work and he disappeared. I'm hoping to hire someone to figure out the issues and get the code working properly.

Please contact me and I will forward the source code and we can discuss the project further.
