Chapter 20, Problem 20.12PE
Program Plan Intro

Clone PriorityQueue

Program plan:

  • Import the required packages into the program.
  • In the Exercise20_12 class,
    • In the main() method,
      • Create two objects for Priority Queue.
      • Add the items into the queue.
      • Create another object for Priority queue by clone() method.
      • Display the result.
  • In the MyPriorityQueue() class,
    • Define the clone() method.
      • Create an object for MyPriorityQueue.
      • Loop execute until the item. If yes,
        • Call the offer() method.
      • Return the queue.

JAVA CODE Learning Objectives: Detailed understanding of the linked list and its implementation. Practice with inorder sorting. Practice with use of Java exceptions. Practice use of generics.   You have been provided with java code for SomeList<T> class.  This code is for a general linked list implementation where the elements are not ordered.  For this assignment you will modify the code provided to create a SortedList<T> class that will maintain elements in a linked list in ascending order and allow the removal of objects from both the front and back.  You will be required to add methods for inserting an object in order (InsertInorder) and removing an object from the front or back.  You will write a test program, ListTest, that inserts 25 random integers, between 0 and 100, into the linked list resulting in an in-order list.  Your code to remove an object must include the exception NoSuchElementException.  Demonstrate your code by displaying the ordered linked list and…
3. Define a Pair class using Java Generics framework a. Properties: first, second b. Constructors: Create 2 different constructor with different initialization parameters c. Methods: setFirst(), setSecond(), getFirst(), getSecond(); d. Test Pair class print out the value of Pair instance: i. Define a Pair instance and assign (10,10.1) to the pair; ii. Define a Pair instance and assign (8.2, "ABC") to the pair; iii. Define an array holding[] of Pair class. 1. holding has 100 elements; 2. Assign (int, double) to array by using loop -> (0, 100.0), (1, 99.0), (2, 98.0), ..., (99, 1.0).
Use Python for this question. Also please comment what each line of code means for this question as well: Inheritance (based on 8.38) You MUST use inheritance for this problem. A stack is a sequence container type that, like a queue, supports very restrictive access methods: all insertions and removals are from one end of the stack, typically referred to as the top of the stack.  A stack is often referred to as a last-in first-out (LIFO) container because the last item inserted is the first removed.  Implement a Stack class using Note that this means you may be able to inherit some of the methods below.  Which ones?  (Try not writing those and see if it works!) Constructor/_init__ - Can construct either an empty stack, or initialized with a list of items, the first item is at the bottom, the last is at the top. push() – take an item as input and push it on the top of the stack pop() – remove and return the item at the top of the stack isEmpty() – returns True if the stack is empty,…
