Q 4
Computer Science
Write a Java generic Class with user-defined method(s) to exchange the positions of two different elements in an Array List.
Step by step
Solved in 4 steps with 2 images
- Computer Science Approach of this Problem and psedocode: 1.Implement an Array List class of type int using primitive array int[] for internal storage. Don't need generic type. 2.Provide constructor, get(int index), and append(int value) methods. Array should dynamically grow as neededRemove all funcation in c++ The function remove of the class arrayList removes only the first occurrence of an element. Add the function removeAll to the class arrayList that would remove all occurrences of a given element. Also, write the definition of the function removeAll and a program to test this function.Linearly search an array in C++. Private class member array.
- java program: University of Bahrain College of Information Technology Department of Computer Science Second Semester, 2020-2021 ITCS214 / ITCS215 / ITCS216 (Data Structures) Assignment 3 Implement generic class ArrayStack as discussed in the lectures having following methods: constructor, push, pop, peek, isEmpty, copy constructor, reallocate (private method). Also add following methods to this class: size: returns number of elements in the stack. contains: Search an element in the stack. If found returns true, else returns false. clear: Deletes all elements of the stack and make it empty stack. Implement generic class ArrayQueue as discussed in the lectures having following methods: constructor, copy constructor, offer, poll, peek, isEmpty, reallocate(private), iterator. Inner class Iter that implements interface Iterator having methods: constructor, hasNext, next. Also add following methods to the ArrayQueue class: size: returns number of elements in the queue. contains: Search…Design a generic function that returns a minimum element from an array. The function should have two parameters. One is the array of a generic type, and the other is the size of the array. Test the function with an array of int, double, and string values.Wap java code to ArrayList represents an array implementation of a list. The front of the list is kept at array index 0. This class will be extended to create a specific kind of list.
- Computer Science 1. Write a generic method named array_prod() that takes an array of a generic type are returns the product of the values in the elements in the array. Make sure that the generic type extends the Number class. The Number class is defined in the java.lang package. 2. Complete the main() method to find the products of the elements in the provided arrays. Print the results in the main method using 3 decimals.Complete an Array-Based implementation of the ADT List including the following main class:Define arrayClass.
- The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.Write a recursive Java function displayOutIn that displays two items from an array list at one instance from out-to-in. until one or last two items displayed and the process stops. For example, given array A = {15, 74, 106, 10, 9, 86, 34} the displayOutIn function displays the following: 15, 34 74, 86 106, 9 10SOLVE USING JAVA It is required to develop an application in Java to represent Set as a data structure using Java built-in class ArrayList. (A) Write a class called Set to represent a set as an ArrayList and implement various set operations by using methods of class ArrayList. Assume that the elements of the set are integers. This class will have the following instance variables: (a) an ArrayList object called list of type Integer, (b) length: the actual number of elements in the list. This class will have the following methods: (1) Constructor without any parameter (default constructor), which uses a default value of 10 as capacity, creates ArrayList object list and initializes length to 0. (2) Constructor with parameter cap for capacity of the list. Create ArrayList object list of capacity equal to parameter cap and initialize length to 0. (3) Instance method getLength, that returns length. (4) Instance method isEmpty to determine whether the set is empty or not. (5) Instance…
