Java Foundations — Question 27

Which statement is true about a mutator method?

Answer options

• A. It replaces the default constructor.
• B. It returns mutated instance members.
• C. It must be declared private.
• D. It can be used to assign data to instance members.

Correct answer: B

Explanation

The correct answer, B, is true because a mutator method is designed to modify the values of instance members. Options A and C are incorrect as mutator methods do not replace constructors or need to be private, and option D, while partially true, does not accurately describe the primary function of mutator methods.
