Question<\/h2>\n

In Java, which comparison about BlockingQueue and Producer-Consumer is accurate?<\/p>\n

    \n
  1. There is no practical difference in behavior, performance, or API design when BlockingQueue and Producer-Consumer is involved.<\/li>\n
  2. The oldest option related to BlockingQueue and Producer-Consumer is always the right production choice regardless of context.<\/li>\n
  3. It provides stronger workflow coordination than a plain queue because it can block instead of forcing busy polling.<\/li>\n
  4. Differences around BlockingQueue and Producer-Consumer are mostly cosmetic, so correctness and maintainability do not change.<\/li>\n<\/ol>\n

    Hint<\/h2>\n

    Focus on the behavior or tradeoff, not just the keyword.<\/p>\n

    Answer and rationale<\/h2>\n

    Correct answer:<\/strong> C. It provides stronger workflow coordination than a plain queue because it can block instead of forcing busy polling.<\/p>\n

    It provides stronger workflow coordination than a plain queue because it can block instead of forcing busy polling. This is the comparison that usually separates memorization from understanding.<\/p>\n
