How did you go about testing your program? What were the results of that testing?

The results of my testing were inproved from the previous day. However i think there maybe a way to ensure better results. I ntend to isolate the error causing my project failure. I also intend to return at lunch so as to work on it. There may be other reasons causing my failure. I also think that java should be a double period so as to allow us more time to complete programs
