Which of these access modifiers must be used for the main() method?Options: Pick one correct answer from belowprivatedefaultpublicprotected

The correct access modifier that must be used for the main() method in Java is public.

Explanation:

1. Public Access Modifier:

   • The main() method must be declared as public for the Java Virtual Machine (JVM) to execute it. Being public allows the JVM to access the main() method from anywhere.

2. Why Others are Incorrect:

   • private: If main() is declared as private, the JVM won't be able to access it, leading to a runtime error.
   • default: A default (package-private) access modifier would restrict the access to classes within the same package, which is not suitable as the JVM may not find it.
   • protected: Similar to default, this would restrict access and is not appropriate for the main() method, as it needs to be accessible globally.

Final Answer

The main() method must be declared as public.
