  3. Heap

  4. Register

    5. Answer:

  1. Flow control

  2. Recursion

  3. Methods

  4. Loops

    5. Answer:

    Loops
    Solution:

    Loops or iterations are better memory-optimized than Recursion technique that solely depends on the Stack memory.

Question: 4 -

Java uses Stack type memory instead of Heap type memory in implementing Recursion because of ___ feature of STACK.

Options:

  1. None of these

  2. LIFO (Last In First Out)

  3. FIFO (First In First Out)

  4. Round Robin

    5. Answer:

    LIFO (Last In First Out)
    Solution:

    Recursion unwinds and completes all methods from the latest to the oldest. So, it requires the LIFO strategy offered by Stack memory.
