Write down a sequence of line numbers that represent a correct implementation of the following set method in ArrayList. For example, 12345. public E set (int index, E e) Line 1: elements[index] e; Line 2: throw new IndexOutOfBoundsException(); Line 3: return oldElement; Line 4: if (index = size) Line 5: E oldElement = elements[index]; An incorrect implementation of a Stack class is provided below. Write down a correct sequence of line numbers from top to bottom. For example, 123. public class Stack extends ArrayList { public void push (EO) Line 01: { return remove(size()-1); } public E peek Line 02: { add(0); } public Epop() Line 03: { return get(size()-1); } }
