1. Write a class named Triangle, containing: Three double data fields named side1, side2, and side3 with default values 1.0 to denote three sides of the triangle. A no-arg constructor that creates a default triangle. A constructor that creates a triangle with the specified side1, side2, and side3. A method named getArea() that returns the area of this triangle. A method named getPerimeter( that returns the perimeter of this triangle. A method named toString() that returns a string description for the triangle. The formula to compute the area of a triangle is shown below, s = (sidel+side2+ side3) / 2 area = Js(s- sidel)(s- side2)(s– side3) The toString() method is implemented as follows: return "Triangle: sidel sidel + " side2 = " + side2+ " side3 = " + side3; = " Write a test program named TestTriangle that creates a Triangle object with sides 1, 1.5, 1, an displays the area, perimeter, and the description for the triangle.

In the class definition, initialize the private fields owner (string), rating (integer), and state (string) with the default values "Unstated", -1, and "Undefined", respectively. Ex: If the input is Ken 4 NY, then the output is: Default values: Name: Unstated's Food Truck, Rating: -1, State: Undefined After mutator methods: Name: Ken's Food Truck, Rating: 4, State: NY Note: The class's print() method is called before and after the input is passed to the setters.

Java Question - Using the bottom code, create another class named "DigitalBook" as a subclass of the given "Book" class. Then, Make sure that the "DigitalBook" class contains two constructors: (1) one is the default constructor that takes no parameter, and (2) the other is a parameterized constructor that take 6 parameters. Be sure to use the “super” keyword in the constructors of the "DigitalBook" class. In the “main()” method of the “EX12_1” class, create four instances: “b1”, “b2”, d1”, and “d2”. Let “b1” and “b2” be the instances of the “Book” class, and let the “d1” and “d2” be the instance of the “DigitalBook” class. Be sure to use the specified constructor (as shown in attached picture) to initialize these instances. The Final Output is shown in the attached pictures. Please make sure that no errors show up in the Java Compiler when testing the code. Thank you. Add the following code to the "class Book" code (Below the ___ line). public class EX12_1{public static void…

D Create a class Sum with the following fields, constructors and methods:Fields: create two integer fields Constructors:- a no-argument constructor- a constructor with two parameters Methods:- write a getter to return the sum of fields- Create 4 overloaded calculate methods 1. method receives two integer parameters and returns the sum 2. method receives four integer parameters and returns the sum 3. method receives two double parameters and returns the sum 4. method receives two String parameters and returns the sum Create a demo class to test the two constructors, all the methods and display the returned values. You can hard code the parameters values. Make sure the four methods created are toverloaded i.e. same method name for all four.
I need to write a jave program to keep track of a team sport. Write a class, Team.java, that has the following: * two private instance variables: a String named color and an int named score. * a default constructor with no parameters that initializes color to "Red" and score to zero. * a constructor that takes two parameters (one for each instance variable) and sets the values of the instance variables. * a public getter and setter method for each instance variable. * a toString method that returns the color and score in the following format: "Red Team with 0 points."
Create a class named Lease with fields that hold an apartment tenant’s name, apartmentnumber, monthly rent amount, and term of the lease in months. Include a constructor thatinitializes the name to “XXX”, the apartment number to 0, the rent to 1000, and the term to12. Also include methods to get and set each of the fields. Include a nonstatic methodnamed addPetFee() that adds $10 to the monthly rent value and calls a static methodnamed explainPetPolicy() that explains the pet fee. Save the class asLeaseYourlastname.java. Replace ‘Yourlastname’ with your real last name.b) Create a class named TestLease whose main() method declares four Lease objects. Call agetData() method three times. Within the method, prompt a user for values for each fieldfor a Lease, and return a Lease object to the main() method where it is assigned to one ofmain()’s Lease objects. Do not prompt the user for values for the fourth Lease object, but letit continue to hold the default values. Then, in main(), pass…
Create a class Course, which has one field: String courseName Create the constructor, accessor, and mutator for the class. Then, in the main method of this class, create an instance of the class with the name "CST1201". Write an equivalent while statement to replace the following for statement for (int i=2; i<100; i=i+2) { System.out.println(i); }
Create a new class called Dog that is derived from the Pet class given in Listing 6.1 of Chapter 6. The new class has the additional attributes of breed (type String) and boosterShot (type boolean), which is true if the pet has had its booster shot and false if not. Give your classes a reasonable complement of constructors and accessor methods. Write a driver program to test all your methods, then write a program that reads in five pets of type Dog and displays the name and breed of all dogs that are over two years old and have not had their booster shots.
Please in pyth coding with correct indentation 4a) Given that you have a Liquid class that can be initialized with any amount of gallons, liters, ounces, etc, write the first line of the method that will allow you to add together two Liquid objects using operator overloading. Again, write ONLY the first line (method definition) – you do NOT have to write the entire method. 4b) Given that you have L1 and L2 which are instances of the Liquid class, write a line of code that uses operator overloading to add them together and assign the result to L3.
please use java to answer the following question Design and implement a class named Triangle that extends GeometricObject. The class contains: Three double data fields named side1, side2, and side3 with default values 1.0 to denote three sides of the triangle. A no-arg constructor that creates a default triangle. A constructor that creates a triangle with the specified side1, side2, and side3. The accessor methods for all three data fields. A method named getPerimeter() that returns the perimeter of this triangle. A method named toString() that returns a string description for the triangle. The toString() method is implemented as follows: return "Triangle: side1 = " + side1 + " side2 = " + side2 + " side3 = " + side3; Write a test program that prompts the user to enter three sides of the triangle, a color, and a boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties…
