Use getter and setter to set the instance variables. Create a class with following attributes: The car's make The car's model The car's year Now let's identify the class's methods. Specifically, the actions are: Constructor of Car class Set and get the car's make Set and get the car's model Set and get the car's year Now create few instance of the Car in a Test class. Use getter and setter to set the instance variables.1- Write a Java class that models a Vehicle. There are three types of vehicles (Sedan, SUV, Truck). Every vehicle object should also contain an instance variable that can be used to store the time at which the vehicle has entered the car parking building (Hint: use the java.util.Date class to represent the time). In addition to the constructors, you should provide the following methods: public double getDuration(Date exitTime) this method will return the duration (in minutes) from the time the vehicle entered the parking until the given exitTime. public String getType() this method will return either Sedan or SUV or Truck based on the vehicle type. public void setType(String type) this method will set the type of the vehicle to either Sedan or SUV or Truck. public void setEntryTime(Date entryTime) this method will set the time at which the vehicle has entered the parking.Task Performance Amount Due Objective: At the end of the activity, the students should be able to: • Apply method overloading in a program. Procedure: 1. Develop a simple program for an individual savings account. Create two (2) classes named AmountDue (no class modifier) and RunAmountDue (public). 2. For the AmountDue class, create three (3) overloaded methods named computeAmountDue based on the following conditions: With a single parameter: It represents the price of one (1) item ordered. Add 12% tax and return the total due. • With two (2) parameters: These represent the price of an item and the quantity ordered. Multiply the two (2) values, add 12% tax, and return the total due. With three (3) parameters: These represent the price of an item, the quantity ordered, and the discount amount. Multiply the quantity and price, deduct the discount amount, add 12% tax, and return the total due. 3. For the RunAmountDue class, import the Scanner class to be able to use the nextDouble()…
- Design/code/test a Java program containing an abstract the class absWelcome. This class should contain: 1. A public abstract void method (you name it) that is empty 2. A public regular method (you name it) that prints "Welcome to " Next, create a subclass clsHello that extends absWelcome. This class should contain: • A public regular method (you name it) that prints "Java Programming" Finally, inside the Main class create an object (you name it) from the clsHello class. Use this new object reference to: 1. Output "Welcome to " from the abstract class 2. Output "Java Programming" from the subclass Your output should resemble that shown below >sh -c javac -classpath -type f-name '*.java') java -classpath :targe Welcome to Java ProgrammingPYTHON: 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, 2000 I have the code but I am getting errors that I can't seem to get rid of any suggestions would be appreciatedCreate the following class diagram: The print method in: - Author prints the Authors data - Page prints page no and text - Textbook prints the subject and all pages - Novel prints the genre and all pages The toString method in: - Book returns title and authors - textbook returns subject in additions to super toString - Novel genre in additions to super toString Test your implementation create objects of different types example : - Create a book of type Novel which has many pages and several authors - Create a book of type Textbook which has many pages and several authors - Access these objects polymorphically, variable of class book contains objects of its subclasses Textbook and novel - Print a hall book - Print a single page of a book - Print the book and its authors
- Java Programming Create your own class that illustrates the use of encapsulation. Make sure to include at least one setter and one getter for the classJAVA PROGRAMMING: Lesson – Overloading Constructors 1. a .Create a class named Circle with fields named radius, area and diameter. Include a constructor method that sets the radius to 1. Also, include methods named setRadius(), getRadius(), computeDiameter() which computes a circle’s diameter and computeArea which computes a circles area (The diameter of a circle is twice its radius and the area is 3.14 multiplied by the square of the radius. b. Create a class named TestCircle whose main() method declares 3 Circle objects. Using the setRadius() method, assign one circle a small radius value and assign another circle a larger radius value. Do not assign a value to the radius of the 3rd circle; instead, retain the value assigned at the constructor. Call computeDiameter() and ComputeArea() for each circle and display the results. Provide your own screen display.30. True or False: The parameterized constructors of Java does not accept any parameters instead, using these constructors the instance variables of a method will be initialized with fixed values for all objects. False True Give an explanation for the answer. Thank you
