Implement a function to add an element before the first element. c. Implement a function to add an item after the last one element. d. Implement a function to output an element of the list. e. Implement a function to output the entire list. f. Implement a function to output the number of elements. G. Implement a function to delete an item. H. Implement a function to clear the entire list. I. Implement functionality to search for one or more students by first name, last name, matriculation number or course of study. J. Implement functionality to sort the records of the student, matriculation number and course according to two self-selected sorting methods.2 //please write it in java This is a circular doubly linked list. It starts at the head pointer (Head). Write a function that adds a node (P) at the nth location away from the Head keeping the circle connected. For example, based on the image, the list is: C, D, B, A After calling addNthNode(Head, P, 2), the list becomes C, F, D, B, A Note that if the position is 1 then the Head should be updated. Your code should validate parameters, and handle edge cases. void addNthNode (Node Head, Node P, int position){ // your code goes here }Create a TestStack project. Add a Stack class with all of the methods implemented and commented (constructor, push, pop, is empty, clear, peek, toString). Create a TestStack class with main(). main() should use your Stack class to do one of the following: OPTION A) Use your stack class to reverse a user inputted string. A palindrome is a word that reads the same backwards as it does forwards. For example, madam is a palindrome, hello is not. Use your stack class to test if an input string is a palindrone or not. OPTION B) Use your new Stack to add a function that checks for balanced parenthese in an equation. Use these three equations, plus one of your own to test your code. ((3^2 + 8)*(5/2))/(2+6) ((3^2 + 8)*(5/2))/(2+6)) (((3^2 + 8)*(5/2)/(2+6) When encountering a left parenthese, push it on the stack. Pop one off when you encounter a right parenthese. Return true or false depending if parentheses are balanced or not (stack is empty after last right parenthese causes a…
- In PriorityQueue.java, write code for the following new functions:1. public boolean add( PriorityQueueNode x )This function adds a new node x to the priority queue. The node is added tothe heap by comparison of the rating attribute. It involves the “percolateup” process and returns true when finished. 2. public PriorityQueueNode remove( )This function removes the minimum element of the priority queue and returnsit. It involves a call to percolateDown( int hole ). 3. private void percolateDown( int hole )This function takes the position of the next available hole in the priority queueand uses it to bubble the elements through the heap until the heap property isrestored. 4. public void display( )This function prints out a formatted tree representation of the priority queueshowing only the rating of each node. The output should resemble that of atree. Tip: you may use the StringBuilder class and the Stringformat( ) method.
