Hi Im having issues finishing these methods on linked list. I need help thank you!

package structures; public class DoublyCircularLinkedListImplementation> implement:s DoublyCicularLinkedList protected int size-*; public DoublyCircularLinkedListImplementation() /I TODO Override public int size) return size; Override public void add(T element) ( // Adds element to this list Override public boolean remove(T element) // Removes an element e from this list such that e.equals (element) // and returns true; if no such element exists, returns false //boolean contains (T element); // Returns true if this list contains an element e such that // e.equals(element); otherwise, returns false Override public boolean contains (T element) // Returns true if this list contains an element e such that // e.equals(element); otherwise, returns false override public T get (T element) ( // Returns an element e from this list such that e.equals(element) // if no such element exists, returns null // String toString); // Returns a nicely formatted string that represents this list. Override public void reset) / Initializes current position for an iteration through this list, // to the first element on this list 1
