I’m stuck on a Computer Science question and need an explanation.

Scenario

We have a linked list containing some elements and we need to build a string of the form [3,6,4,2,4]. If the list is empty, it should output [].

Aim

Write code in Java for traversing the linked list.

Steps for Completion

  1. Write a toString() method in the LinkedList class as follows:

public String toString() {

// …

}

  1. Use a while loop to traverse the linked list.

Grading

Complete each task listed below. Each task contains automated checks which are used to calculate your grade. When you have completed each task by clicking the checkbox, open the task list panel on the left navigation bar and click the “Submit” button.

Tasks

Write the toString() method in the LinkedList class.

1

Use a while loop to traverse the linked list to add the nodes to print to the console. Wrap the list of nodes in opening and closing brackets separated by commas : [node1, node2, node3].
