- Write the statement to declare the constructor with two parameters and assign the values by creating an object for the class "Company". in javaIn this exercise, you have to calculate the student's total marks using the concept of Classes Problem Statement# Write a Java class called Student with ● private fields: ○ name(String type) ○ mark1 and mark2 (double type) And methods: ● getMarks(int markNumber), a method which should return mark1 if markNumber equals 1 and mark2 otherwise. ● calcTotal() method should take the two marks entered and return their sum. Also define two constructors: ● A default constructor that takes no parameters and initializes the values to zeros and null. ● A constructor that takes the three variables and sets them as the values of the appropriate fields. Input# Name of the student and the marks obtained in the first and second tests Output# Sum of both marks Sample Input# Student student = new Student("Jack", 60, 70); Sample Output# getMarks(1) => 60 getMarks(2) => 70 calcTotal() => 130.0 Part of solution class Student { // Define private fields here public Student() { // Write…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*/}
- You are in process of writing a class definition for the class Book. It has three data attributes: book_title, book_author, and book_publisher. The data attributes should be private. In Python, write a setter/mutator method and a getter/accessor method for book_title(only) that will be part of your class definition. Note: You do not need to write the entire class definition. Just the two methods mentioned.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…in this example we have two constructors with the same arguments which is going to confuse the compiler which constructor to call when we call it in main code by an object what is the solution for this problem without changing the number of the arguments in the constructors
- Note: Write a Java program given below Question # 1: Define a class for Students with field name, age, marks. Define getter and setter for all the fields. In the setter method, if age is less than 0, print that Age is less than zero. Similarly, if marks is less than zero or greater than 100, print in correct marks and don’t assign marks to member variable. In the Test class, create student’s object and assign the marks and age to appropriate values. Try assigning incorrect values to check if getter and setter methods work as expected.Suppose that the class Pet has a field called name that is of the type String. Write an assignment statement in the body of the following constructor so that the name field will be initialized with the value of the constructor’s parameter. public Pet(String petsName) { }Write a tester program to test the mobile class defined below. Create the class named with your id (for example: Id12345678) with the main method. Create two mobiles M1 and M2 using the first constructor. Print the characteristics of M1 and M2. Create one mobile M3 using the second constructor. Change the id and brand of the mobile M3. Print the id of M3. The programming I'm using is java. So, I'll be much appreciated if the answer was in java plus, Can you solve with the entry below? public class Mobile { private int id; private String brand; public Mobile() { id = 0; brand = ""; } public Mobile(int n, String name) { id = n; brand = name; } public void setBrand(String w) { brand = w; } public void setId(int w) { id = w; } Public int getId() { return id; } public String getBrand() { return brand; } }
- Got stuck on this for my daily coding practice. I would like to understand it in Java. Given main(), complete the FoodItem class (in file FoodItem.java) with constructors to initialize each food item. The default constructor should initialize the name to "Water" and all other fields to 0.0. The second constructor should have four parameters (food name, grams of fat, grams of carbohydrates, and grams of protein) and should assign each private field with the appropriate parameter value. Ex: If the input is: Water the output is: Nutritional information per serving of Water: Fat: 0.00 g Carbohydrates: 0.00 g Protein: 0.00 g Number of calories for 1.00 serving(s): 0.00 Ex: If the input is: M&M's 10.0 34.0 2.0 3.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 3.0 is the number of servings, the output is: Nutritional information per serving of M&M's: Fat: 10.00 g Carbohydrates: 34.00 g Protein: 2.00…I am having trouble with doing this code on Python: Define the Artist class with a constructor to initialize an artist's information and a print_info() method. The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. print_info() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise. Define the Artwork class with a constructor to initialize an artwork's information and a print_info() method. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Ex: If the input is: Pablo Picasso 1881 1973 Three Musicians 1921 the output is: Artist: Pablo Picasso (1881-1973) Title: Three Musicians, 1921 If the input is: Brice Marden 1938 -1 Distant Muses 2000 the output is: Artist: Brice Marden, born 1938 Title: Distant Muses, 2000In the absence of any constructors, what will happen in Java? O Send out a cautionary note. Send out a message to the user indicating that something went wrong. Create a default constructor on the fly. O Create a constructor with an int return type on demand, rather than manually.
