Dyanmic arrays aren't any different from static arrays except that dynamic arrays are allocated on the heap and not the stack. No functional language I have ever encountered implemented an array as a linked list. That would be extremely inefficient in both space and time as compared to an array.
Certainly when I disassemble the output from my C++ compiler, I see dynamic array accesses computing pointers through offsets from the array base. Changing the length of the array requires a memory reallocate operation, not an allocate node operation. After working with JNI, I am quite sure that Java works the same way.
