numUniqueValues ♡ Language/Type: Related Links: Java Set collections List Write a method named numUnique Values that accepts a List of integers as a parameter and returns the number of unique integer values in the list. For example, if a list named 1 contains the values [3, 7, 3, -1, 2, 3, 7, 2, 15, 15], the call of numUniqueValues (1) should return 5. If passed the empty list, you should return 0. Use a Set as auxiliary storage to help you solve this problem. Do not modify the list passed in. 6 7 8 9 10 Method: Write a Java method as described, not a complete program or class. 12345

Lab 19 Building a linked list Start this lab with the code listed below. The LinkedList class defines the rudiments of the code needed to build a linked list of Node objects. You will first complete the code for its addFirst method. This method is passed an object that is to be added to the beginning of the list. Write code that links the passed object to the list by completing the following tasks in order: 1. Create a new Node object. 2. Make the data variable in the new Node object reference the object that was passed to addFirst. 3. Make the next variable in the new Node object reference the object that is currently referenced in variable first. 4. Make variable first reference the new Node. Test your code by running the main method in the LinkedListRunner class below. Explain, step by step, why each of the above operations is necessary. Why are the string objects in the reverse order from the way they were added? public class LinkedList { private Node first; public LinkedList () {…
