Answer 1

Follow proper naming conventions of java, this will help you now in this problem by solving the conflict and will avoid some other bugs too.Also

1. For classes, use UpperCamelCase.
2. For class members and local variables use lowerCamelCase
3. For packages, use reverse URI, e.g. org.acme.project.subsystem
4. For constants, use ALL_CAPS.
