1. Java automatically imports java.lang; no explicit import statement is needed.

2. Public access is obtained with the keyword public, and it allows access by any program. Private access is obtained with the keyword private, and it allows access only by the methods of the class. Package access is obtained with no keyword, and it allows access within the package but not elsewhere.
