Define class Shape, 2DShape and 3DShape as per UML class diagram given. 2. Define all mutator methods(set and get) for all classes. 3. Define methods calArea() with formula area - width * length for 2DShapes. 4. Define methods calArea() with formula calvolume, volume = width*length*height for 3DShapes. In the main program, declare and set data in 1 object of 3DShapes. Create an array OR ArrayList of 2DShapes, set and display the info of all objects as shown in the output. 5.
The Temperature class is an abstract class with two abstract methods. Create the Conversion class which inherits from Temperature. Use the formulas below to help with the temperature conversions. CODE: abstract class Temperature { public abstract double celsius(double temp); public abstract double fahrenheit(double temp);} //add class definitions below this line //add class definitions above this line public class Exercise3 { public static void main(String[] args) { //add code below this line Conversion c = new Conversion(); //add code above this line }}
JAVA CODE Write a java set of classes that could be used to do simple calculations on geometricobjects. The set should include the following classes: a) Shapes ,containing abstract methods( a methods that is declared without animplementation) area and perimeter b) Rectangle, a subclass of Shape, containing a constructor (with parameters forlength and width) along with methods area and perimeter. c) Triangle, a subclass of Shape, containing a constructor (with parameters for the three sides of a triangle) along with methods area ( s = (a+b+c)/2, A = sqrt( s(s-a)(s-b)(s-c) ) ) and perimeter d) Square, a subclass of Rectangle, containing a constructor (with a parameter for thelength of a side) and methods that invoke the methods of the Rectangle class todetermine the perimeter and area of a square.

public class Father { public String name; public int age; // customer name Father(){ name=”Hassan”; age=50;} public void display(){ System.out.println(“Name:”+name); System.out.println(“Age:”+age); } } 1. Based on Figure 3, create a class named Child that inherits the Father class. Declare an instance name location (String) for class Child. 2. Define a constructor in class Child and give an appropriate initial values for the instance (name, age, location). 3. Define a method display () in class Child, execute the display ( ) method in superclass using the keyword super. Method display ( ) in class Child should print the information of name, age and location 4. Create other class named Main for the main method and create 2 objects for the 2 classes (Father and Child). Then execute the display ( ) method for Father and Child. Example of the output as in Figure 4: Father's info: Name: Josh Age: 50 Child's info: Name: Christy Age: 20 Location:…
