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:

- [JAVA] Answer these questions according to the UML class schema given above. You may need to extract hidden information from the schema and add necessary code. You don’t have to consider inconsistencies other than the ones explicitly stated in questions. You will be writing some part of hotel management software. Pay attention to the following details about the program logic when writing your code: Question 1: Write the source code of classes CriticalException and NonCriticalException. Question 2: Write the source code of classes Person and Employee. Question 3: Write the source code of class Room. The details of its methods are as follows: setCapacity: If one attempts to set a negative capacity or a capacity greater than maxRoomCapacity, a CriticalException is generated. setDailyRate: A room’s daily rate must not be changed while there are guests in it. Otherwise, a NonCriticalException is generated. Constructor must use the setter methods described above. addGuest: A guest must not…Select the pair that correctly completes this sentence. In Java we derive classes from the _?__ class. The derived class is called a __?__ class. parent and child main and child method and sub none of theseDefine the classbankAccountto store a bank customer’s account number and balance. Suppose that account number is of type int, and balance is of type double. Your class should, at least, provide the following operations: set the account number, retrieve the account number, retrieve the balance, deposit,and withdraw money, and print account information. Add appropriate constructors. b.Every bank offers a checking account. Derive the class checkingAccountfrom the classbankAccount(designed in parta). This classinherits members to store the account number and the balance from the base class. A customer with a checking account typically receives interest, maintains a minimum balance, and pays service charges if the balance falls below the minimum balance. Add member variables to store this additional information. In addition to the operations inherited from the base class, this class should provide the following operations: set interest rate, retrieve interest rate, set minimum balance,…

- Computer Science practice question-JAVA CarbonFootprint Interface: Polymorphism Using interfaces, we can specify similar behaviors for possibly disparate classes. Governments and companies worldwide are becoming increasingly concerned with carbon footprints (annual releases of carbon dioxide into the atmosphere) from buildings burning various types of fuels for heat, vehicles burning fuels for power, and the like. Many scientists blame these greenhouse gases for the phenomenon called global warming. Create three small classes unrelated by inheritance—classes Building, Car and Bicycle. Give each class some unique appropriate attributes and behaviors that it does not have in common with other classes. practice an interface CarbonFootprint with a getCarbonFootprint method. Have each of your classes implement that interface, so that its getCarbonFootprint method calculates an appropriate carbon footprint for that class. Practice an application that creates objects of each of the…JAVA - Assume your task is to write a program that simulates a vending machine. Users select a product and provide payment. If the payment is sufficient to cover the purchase price of the product, the product is dispensed and change is given. Otherwise, the payment is returned to the user. Name an appropriate class for implementing this program. Name two classes that would not be appropriate and explain why.PART B: JUnit Testing Write a Java program according to the following: Create a Multiple.java class. Create the following two static methods (with return type float): SquareRoot() and CubeRoot(). SquareRoot) method should take two arguments and return the float value at the end. CubeRoot() method should take three arguments and return the float value at the end. Create a test class with the name MultipleTest.java. In this class, import the following libraries at the top of this file import org.junit. Before; import org.junit. Test; import static org.junit.Assert.assertEquals; Create an object of Calculator.java class by writing the following code in CalculatorTest.java class: private Multiple multiple; @Before public void setup() {this.multiple new Multiple():) 4.
