Multiple choiceMediumchapter-20-curatedpremiumengineering-interviewsjvm-trivia
Answer and explanation
Correct answer
D. To enhance performance and security, especially in multithreaded contexts.
Why
String immutability in Java enhances performance by allowing string literals to be reused via the string pool, and it provides security by preventing string value changes after creation. This is particularly beneficial in multithreaded applications, where shared data integrity is crucial.
