Помогите пожалуйста по Java!

это чат gpt сделал public class LinkedList<T> {

private Node<T> head;
private int size;

private static class Node<T> {
T data;
Node<T> next;

Node(T data) {
this.data = data;
this.next = null;
}
}

public void add(T element) {
Node<T> newNode = new Node<>(element);

if (head == null) {
head = newNode;
} else {
Node<T> current = head;
while ( current.next != null) {
current = current.next ;
}
current.next = newNode;
}

size++;
}

public T get(int index) {
if (index < 0 || index >= size) {
throw new IndexOutOfBoundsException("Index out of range: " + index);
}

Node<T> current = head;
for (int i = 0; i < index; i++) {
current = current.next ;
}

return current.data;
}

public void remove(int index) {
if (index < 0 || index >= size) {
throw new IndexOutOfBoundsException("Index out of range: " + index);
}

if (index == 0) {
head = head.next ;
} else {
Node<T> previous = head;
Node<T> current = head.next ;
for (int i = 1; i < index; i++) {
previous = current;
current = current.next ;
}
previous.next = current.next ;
}

size--;
}

public int size() {
return size;
}
}
