OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
In Java, which condition occurs when the same object appears as both an input and output parameter?
- copy constructor
- aliasing
- operator overloading
- type conversion

- SELECT ALL of the instance fields/variables from the class declaration below./** * A constructor that takes the user's ID. If the ID is null, or * longer than 32 characters, or it does not start with "@", * throw an IllegalArgumentException. * The ID may contain any ASCII characters, so you don't have to * worry about checking for special characters. Also do not worry * about checking whether any other user has the same ID. * * All other instance variables should be initialized appropriately. * * @param userID the ID of the new user */ public TwitterUser(String userID) { throw new UnsupportedOperationException("Implement this"); }In a Java class, the method that creates an object by using the new operator is called the ___. mutator accessor toString constructor
- in java Create a class for Student and implement all the below listed concepts in your class. Read lecture slides for reference. Class Name: Student 1. Data fields studentID name email majorDepartmentSelect proper datatypes for these variables. 2. Constructors – create at least 2 constructors No parameter With parametersSet id and name using the constructor with parameters. 3. Methods toString method : To print the details of the Student. Setter and getter methods 4. A static variable count : To keep the count of Student objects5. Visibility Modifiers: private for data fields and public for methods 6. Write some test cases in main methodProblem Description and Given Info For this assignment you are given the following Java source code files: IStack.java (This file is complete – make no changes to this file) MyStack.java (You must complete this file) Main.java (You may use this file to write code to test your MyStack) You must complete the public class named MyStack.java with fields and methods as defined below. Your MyStack.java will implement the IStack interface that is provided in the IStack.java file. You must implement your MyStack class as either a linked list or an array list (refer to your MyArrayList and MyLinkedList work). Your MyStack must not be arbitrarily limited to any fixed size at run-time. UML UML CLass Diagram: MyStack Structure of the Fields While there are no required fields for your MyStack class, you will need to decide what fields to implement. This decision will be largely based on your choice to implement this MyStack as either an array list or a linked list. Structure of the Methods As…What is not the use of “this” keyword in Java? a) Referring to the instance variable when a local variable has the same name b) Passing itself to the method of the same class c) Passing itself to another method d) Calling another constructor in constructor chaining
- A. You can invoke an instance method or reference an instance variable from a static method. B. You can invoke a static method or reference a static variable from an instance method. * Options: Only A is true Both A and B are true Both A and B are false Only B is true Note: Answer the correct optionWhich of the following is the most direct example of how information hiding is supported in Java? constructors inheritance member functions public and private specifiersJava programming If we send an int parameter to a method, and the parameter value is changed inside the method, will that affect the original value?
- please help me understand this code in java (using generic method). More specifically why was item1,item2, item3 parameter names never used again and what is the purpose of this line of code: TheType tripleMin(TheType item1, TheType item2, TheType item3) {In Java, what allows for the manipulation of data variables in a class? Group of answer choices: Class Instance methods Public interface EncapsulationIn a Java class, this method has the same name as the class and is called when an object is created (instantiated)____
