Quick Answer
Packages group related classes and provide namespace separation. Access control per package: public (everywhere), protected (package + subclasses), default/package-private (same package only), private (class only). Classes in the same package can access each other's package-private members without importing. Use packages to organize code and control what's part of your public API.
Answer
Packages group related classes. Access modifiers: public, private, protected, default. Improves modularity and avoids naming conflicts.
