1. add(E e): Adds an element to the end of the list.
2. addAll(Collection<? extends E> c): Adds all elements from a collection to the end of the list.
3. set(int index, E element): Replaces an element at a specified index.
4. remove(int index): Removes an element at a specified index.
5. remove(Object o): Removes the first occurrence of a specified element.
6. size(): Returns the number of elements in the list.
7. lastIndexOf(Object o): Returns the index of the last occurrence of a specified element.
8. iterator(): Returns an iterator over the elements in the list.
9. listIterator(): Returns a list iterator over the elements in the list.

ArrayList Operations

1. Add Elements
   • add(element obj): Adds an element to the end of the list. Used three times.
   • add(int index, element obj): Adds an element at a specified index.
   • add(0, element obj): Adds an element at the beginning of the list.
   • add(size(), element obj): Adds an element at the end of the list.
2. Remove Elements
   • remove(0): Removes the first element from the list.
   • remove(size() - 1): Removes the last element from the list.
   • remove(int index): Removes the element at a specified index.
3. Get Elements
   • get(int index): Retrieves the element at a specified index.
   • get(0): Retrieves the first element of the list.
   • get(size() - 1): Retrieves the last element of the list.
4. Set Element
   • set(int index, element obj): Replaces the element at a specified index with a new element.
5. Traversal Techniques
   • For each loop: Iterates over the elements using a for-each loop.
   • Iterator: Iterates over the elements using an iterator.
   • ListIterator: Iterates over the elements using a list iterator.

LinkedList Operations

1. Add Elements
   • add(element obj): Adds an element to the end of the list. Used three times.
   • add(int position, element obj): Adds an element at a specified position.
   • addFirst(element obj): Adds an element at the beginning of the list.
   • addLast(element obj): Adds an element at the end of the list.
2. Remove Elements
   • removeFirst(): Removes the first element from the list.
   • removeLast(): Removes the last element from the list.
   • remove(int position): Removes the element at a specified position.
3. Get Elements
   • get(int position): Retrieves the element at a specified position.
   • getFirst(): Retrieves the first element of the list.
   • getLast(): Retrieves the last element of the list.
