Can you modify case d and c in main?

import java.util.Scanner;

public class Playlist {

(6) Implement the "Remove song" method. Prompt the user for the unique ID of the song to be removed. (4 pts) Ex: REMOVE SONG Enter song's unique ID: "A 3134 For You" removed (7) Implement the "change position of song" menu option. Prompt the user for the current position of the song and the desired new position. valid new positions are 1 - n (the number of nodes). If the user enters a new position that is less than 1 , move the node to the position i (the head). If the user enters a new position greater than n, move the node to position n (the tail). 6 cases wil1 be tested: Moving the head node ( 1pt ) Moving the tail node ( 1pt ) moving a node to the head (1 pt) Moving a node to the tail (1 pt) Moving a node up the list (1 pt) Moving a node down the list (1 pt) Ex: CHANGE POSITION OF SONG Enter song's current position: Enter new position for song: "Canned Heat" moved to position 2
