Question<\/h2>\n

Which statement about StringBuilder vs StringBuffer is the strongest interview answer?<\/p>\n

    \n
  1. StringBuilder vs StringBuffer is mostly a naming style choice and has little effect on runtime or design.<\/li>\n
  2. StringBuilder vs StringBuffer exists mainly to reduce the number of Java files in a project.<\/li>\n
  3. Both are mutable string helpers, but StringBuffer synchronizes methods while StringBuilder does not.<\/li>\n
  4. StringBuilder vs StringBuffer matters only for frontend frameworks, not for core Java applications.<\/li>\n<\/ol>\n

    Hint<\/h2>\n

    Start with the core rule behind StringBuilder vs StringBuffer.<\/p>\n

    Answer and rationale<\/h2>\n

    Correct answer:<\/strong> C. Both are mutable string helpers, but StringBuffer synchronizes methods while StringBuilder does not.<\/p>\n

    Both are mutable string helpers, but StringBuffer synchronizes methods while StringBuilder does not. This is the base concept interviewers commonly test first.<\/p>\n
