Question

Which of the following is not the four P’s of protection in Java?

• A. Public
• B. Packed
• C. Protected
• D. Private

Hint:

Java access modifiers include {public, protected, private, and default (package-level)} access.

Answer 1

The Correct Option is B

Step 1: Understanding access protection in Java.
Java provides access control mechanisms that help restrict how classes, variables, and methods can be accessed from different parts of a program. These mechanisms ensure data security and proper encapsulation in object-oriented programming.
Step 2: The four P’s of protection.
Java commonly refers to its access control modifiers as the four P’s of protection. These include:
Public: Members declared as public can be accessed from anywhere in the program.
Protected: Members declared as protected can be accessed within the same package and also by subclasses in other packages.
Private: Members declared as private can only be accessed within the same class.
Package (Default): Members without an access modifier are accessible only within the same package.
Step 3: Evaluating the options.
(A) Public: Correct access modifier in Java.
(B) Packed: Incorrect. This is not an access modifier in Java.
(C) Protected: Correct access modifier.
(D) Private: Correct access modifier.
Step 4: Conclusion.
Therefore, the option that is not part of the four P’s of protection in Java is Packed.
Final Answer: Packed
