Here, you need to build linked list by taking user inputs for node data. After building linked list, you need to delete that node which is provided by user from it. So, to build linked list, you need to write one function which will add nodes to list object. To delete node, you need to write delete function. In that function, you can traverse list and you can search the node. If node will found then you need to change links of that node. So that node will be deleted. To print list, you can write separate function. In that unction, you can traverse the list and you can print data of each node. To take user input, you need to use 'Scanner' class. So code will be like import java.util.Scanner; class Node{ public String data; public Node next = null; public Node(String data, Node next) { this.data = data; this.next = next; } public Node(String data) { this(data, null); } public String toString() { return data; }}public class Main{ Node head; // this function will print the list public static void printList(Main list) { Node currNode = list.head; System.out.print("\nLinkedList: "); while (currNode != null) { System.out.print(currNode.data + " "); currNode = currNode.next; } } // this function will delete the node public static Main deleteNode(Main list, String key) { Node currNode = list.head; Node prev = null; // this condition will get executed if head will be the node that needs to be deleted if (currNode != null && key.equalsIgnoreCase(currNode.data)) { list.head = currNode.next; System.out.println(key + " found and deleted"); return list; } // this loop will traverse ths link list while (currNode != null && !key.equalsIgnoreCase(currNode.data)) { prev = currNode; currNode = currNode.next; } if (currNode != null) { prev.next = currNode.next; System.out.println(key + " found and deleted"); } if (currNode == null) { System.out.println(key + " not found"); } return list; } // this function will add node in list public static Main insert(Main list, String data) { Node newNode = new Node(data); newNode.next = null; if (list.head == null) { list.head = newNode; } else { Node last = list.head; while (last.next != null) { last = last.next; } last.next = newNode; } return list; } public static void main(String[] args) { Main list = new Main(); // this is list object Scanner sc = new Scanner(System.in); // here Scanner class object is created while(true) { System.out.print("\nEnter name: "); String data = sc.nextLine(); list = insert(list, data); System.out.println("\nTo continue press 'Y' or to stop press 'N' "); String replay = sc.nextLine(); if(replay.equalsIgnoreCase("N")) { break; } } printList(list); System.out.print("\n\nWhich name do you want to remove: "); String name = sc.nextLine(); list = deleteNode(list, name); printList(list); }}Output of code is

Ask user to enter as many names as he/she wants. Then according to the Node class below to build your link list. The order of list is according to the entering order. public class Node { public String data; public Node next = null; public Node(String data, Node next) { this.data = this.next = next; } public Node(String data) { this (data, null); } public String toString() { return data; } data; } Print the list. Ask user whom he/she wants to remove. Remove the node.
