Which access modifier is used when you write NO keyword in front of a field or method?

Options

1. public: visible to every class in the project
2. private: visible only inside the same class
3. Package-private: visible only to classes in the same package (Correct option)
4. protected: visible to subclasses and the same package

Answer

Package-private: visible only to classes in the same package

Why

Java has four levels of visibility:

• public: everyone.
• protected: same package plus subclasses.
• (no keyword) package-private: only classes in the same package.
• private: only inside the same class.

Good practice (encapsulation): make fields private and expose only what is needed through public methods.

Remember

No keyword = package-private.
