- Java Objects and Linked Data: Select all of the following statements that are true. The Java Class Library's class ArrayList implements the LinkedList interface. In Java, when one reference variable is assigned to another reference variable, both references then refer to the same object. In Java, the "equals"-method that any object inherits can be overwritten to compare objects field by field.Write the definitions of the member functions of the classes arrayListType and unorderedArrayListType that are not given in this chapter. The specific methods that need to be implemented are listed below. Implement the following methods in arrayListType.h: isEmpty isFull listSize maxListSize clearList Copy constructor Implement the following method in unorderedArrayListType.h insertAt Also, write a program (in main.cpp) to test your function.Define a struct fruitType to store the following data about a fruit: Fruit name (string), color (string), fat (int), sugar (int), and carbohydrate (int).

Be sure to use many with identical last years and different prices. Create an ArrayList from the array. Shuffle the ArrayList. Sort the ArrayList first by year and then by price. See page 790-791. Using the forEach method and a lambda expression, print all cars sorted as above. Create a LinkedList from the ArrayList. Create an iterator capable of cycling both forward and backward through the LinkedList. Iterate forward through the entire LinkedList but without generating any output. Then iterate backwards through the LinkedList to print the cars data.Data structure & Algrothium java program Create the following classes: 1. Name.java object class containing two strings attributes first name and last name (and appropriate constructors, setters/getters)2. NicePerson.java object class containing the name object and an ArrayList of string to store the list gifts ( and appropriate constructors, setters/getters). This class would extend the attached NicePersonInterface.java3. Santa.java object class containing one ArrayList of Names to store the naughty names. Another ArrayList of NicePerson to store the nice names and gifts. Add atleast 4 names in each list and display all information.
