We found that we could use a spelling checking library (Jazzy) to find English words in the decrypted text and the program could decide which decryption shift was correct.   We were not able to find the spaces in the decrypted text in the right places, but the program did a good job finding longer words such as forest and not stopping at for, and outlaw instead of out and law as separate words.   We got a deeper understanding of Java itself by just experimenting during the programming. We also learned about the Caesar Cipher, decryption, encryption and cryptography in general.   The whole group learned a lot about teamwork because none of us have worked with a team on a yearlong project before.
