Java Arrays - each element in the array holds a pointer to the next element

Question

The LinkedList Java class uses a doubly linked list to store items.

Does arrays in Java use a sibling list?

Is this how the array and stacks are different in java.

Answer 1

No. An array is just a contiguous block of memory whose length can be checked to make sure that you are not trying to access elements outside the bounds of the array.

To go to a specific element, the virtual machine simply (logically, at least) takes the starting address of the data in the array and adds the index times the element size.

Answer 2

STACK LIFO. , , , .

Answer 3

Arrays are completely different from linked lists. When it comes to a linked list, the difficulty of removing an item from a list is lower than the cost to remove an item from arrays.
