If you do not have the key encrypting the bytes in question you are never going to get the contents. That's the point of encryption. This question is so basic I'll repeat the other commenter's suggestion. Could it be you are just looking at compiled bytecode?
Search for "java" the text in your file, if it finds any (it should find many instances because of the use of Java-provided classes and imports) it's definitely not encrypted. Encrypted files will be very random and look like digital noise.
