Question<\/h2>\n

In Java, which comparison about Doubly Linked Lists is accurate?<\/p>\n

    \n
  1. It supports easier deletions from a known node than a singly linked list, but it uses more memory and pointer maintenance.<\/li>\n
  2. There is no practical difference in behavior, performance, or API design when Doubly Linked Lists is involved.<\/li>\n
  3. The oldest option related to Doubly Linked Lists is always the right production choice regardless of context.<\/li>\n
  4. Differences around Doubly Linked Lists 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> A. It supports easier deletions from a known node than a singly linked list, but it uses more memory and pointer maintenance.<\/p>\n

    It supports easier deletions from a known node than a singly linked list, but it uses more memory and pointer maintenance. This is the comparison that usually separates memorization from understanding.<\/p>\n
