Add the following methods to the ArrayList class that we wrote during lecture. You may call the existing methods in ArrayList if you want, but do not use anything from the built-in java.util.ArrayList class. 1. (3 pts) Write a new method named addAll(ArrayList anotherList) that adds all the elements in anotherList to the back of the calling list. Be sure to reallocate the data array if necessary. anotherList should not be modified. 2. (4 pts) Write a new method named...

How to measure the average performance of sorting algorithms with different sizes and numbers(with arrayList<Integer>) and compare with a graph? I have these methods: //This one receives one size(n) parameter public static ArrayList<Integer> RandomArray(int n){ ArrayList<Integer> randomArray = new ArrayList<Integer>(n); Random rand = new Random(); //--- random number rand.setSeed(System.currentTimeMillis()); for(int i = 0; i < n; i++ ) { //loop for creating...

1. What is output by the following code: ArrayList< Integer > a = new ArrayList< Integer >(); ArrayList b = a; a.add(new Integer(4)); b.add(new Integer(5)); a.add(new Integer(6)); a.add(new Integer(7)); System.out.println(b.size()); A)1 B)2 C)3 D)4 E)5 2. Assume the Student and Employee classes each extend the Person class. The Student class overrides the getMoney method in the Person class. Consider the following code: Person p1, p2, p3; int m1, m2, m3; p1 = new Person(); m1 = p1.getMoney(); // assignment 1...

Pseudocode and PYTHON source code, thanks! Program 1: Design (pseudocode) and implement (source code) a class (name it QuadraticEquation) that represents a quadratic equation of the form of ax2+ bx + x = 0. The class defines the following variables and methods: Private data field a, b, and c that represent three coefficients. A constructor for the arguments for a, b, and c. Three get methods for a, b, and c. Method getDiscriminant()returns the discriminant value, which is disc =...

In class, we discussed the priority queue (PQ) ADT implemented using min-heap. In a min-heap, the element of the heap with the smallest key is the root of the binary tree. On the other hand, a max-heap has as root the element with the biggest key, and the relationship between the keys of a node and its parent is reversed of that of a min-heap. We also discussed an array-based implementation of heaps. In this assignment, your task is to...
