Please help me with this code in Java. Thank you.

you will implement some methods on the SortedLinkedList class provided. This class contains a doubly linked list of integers where the integers are stored in ascending order (from smallest to largest). Please do not change any of the method signatures or other code given (including the package name). public void insert(int i) This method inserts a Node containing data equal to i in the sorted linked list and maintains the property that the list is in sorted order from smallest to largest. The example below illustrates how the number 3 would be inserted into the given SortedLinkedList object. public boolean issorted() This method returns true if the SortedLinkedList object is actually sorted in ascending order. You should think about how you could use this method to guarantee that your insert method is correct
