Question

Read the below statement
We have four classes
1. Class get:
	1. This class will contain a function called getmyInput() that will prompt the user for three Inputs- Length, Width, Height
2. Class getInput:
	1. This class will be a child class fo the get class it will contain a function called InputValues() that will get its three values from the getMyInput() function
3. Class Compute:
	1. This calss will contain three functions called 
		a. calculateArea()
		b. CalculatePerimeter()
		c. CalculateVoluem()
The three function will get their inputs from the InputValues() function and calculate them respectively
4. Class Display Output
	1. This class will contain the function OutputValues() wich will be used to display the results of each calculation

Create a UML diagram and a Java Program for the Above Classes

public class Circle {
    private double radius;

public Circle() {
        radius = 0;
    }

public Circle(double radius) {
        this.radius = radius;
    }

public double getRadius() {
        return radius;
    }

public void setRadius(double radius) {
        this.radius = radius;
    }

public double getArea() {
        return calculateArea();
    }

private double calculateArea() {
        return radius * radius * Math.PI;
    }

public String toString() {
        return "The radius of the circle is: " + radius + ", and the area is: "
                + calculateArea();
    }

public class Rectangle {    
    private static double length;
    private static double width;

public Rectangle() {
        length=0.0;
        width=0.0;
    }

public Rectangle(double l, double w) {
        length = l;
        width = w;
    }

public double FindArea() {
        return length*width;
    }

public double FindPerim() {
        return length*2 + width*2;
    }   
}
