- What are getters and setters? Give an example of each. What is encapsulation? What is a constructor and when is it executed? What does it usually do?Given the following class, I need help writing a constructor that initializes all instance variables using appropriate parameters. I need to make sure it enforces the preconditions public class BrowserTab {private String title;private int id;/*** Creates a BrowserTab* @precondition title != null && id >= 0*/}Create a class Fraction with two integer final fields: numeratorand denominator. Its constructor creates fractions when given valuesfor both, but it has to avoid fractions with null denominators by throwing aNullDenominatorException
- 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 methodTrue or False: If methodA() has an equals() method that overrides the one in the Object class, then in our JUnit test for methodA(), assertEquals() will use the version of equals() in methodA().Why is it necessary for a class to implement a destructor? Fill in the blanks with your response.
- NOTE: Don't Copy from the Chegg, Use this method for a given question 3 LockADT – Show the interface and all abstract methods LockDataStructureClass – Show the following methods: default constructor, overloaded constructor, copy constructor, setX, setY, setZ, alter (change the lock’s combination to the numbers passed) turn (use for loops to show the dial turning), close (locks the lock), attempt (tries to unlock the lock – calls turn( ), inquire (locked or unlocked), current (returns the number the dial is pointing to), toString LockClientDemoClass – You should have a Lock object instantiated and a menu method that displays: 1: set lock combination 2: close lock 3: check status 4: attempt to open lock 5: check what the dial is currently pointing at 6: exit the program Example of turning the lock: First number (17): 0 39 38 37 … 0 39 38 …17 Second number (26): 17 18 19 ... 38 39 0 1 2 … 17 18 19 20 21 22 23 24 25 26 Third number (9): 26 25 24 23 …. 12 11 10 9 (go directly to the…Can you call a constructor from another constructor? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Problem Statement# A class can have multiple parameterized constructors which can call each other. You are given a partially completed code of a Car class in the editor. Modify the parametrized constructor which assigns parameters to the required fields. Input# carName, carModel, carCapacity Output# carName, carModel, carCapacity Sample Input# "Ferrari", "F8", "100" Sample Output# "Ferrari", "F8", "100" Part of solution // Car class class Car { // Private Fields private String carName; private String carModel; private String carCapacity; // Default Constructor public Car() { this.carName = ""; this.carModel = ""; this.carCapacity = ""; } // Parameterized Constructor 1 public Car(String name, String model) { this.carName = name; this.carModel = model; } // Parameterized Constructor 2 public…You have to make a class and in which a variable is present and you have to perform addition of 2 number which is passed from one constructor to another constructor means both are overloaded. You have to make object of that and print the result In java
