Change the below code in Java using JOptionPane and make sure displaying radius, area, and circumference of the circle should work nicely.

Circle.java

import java.text.DecimalFormat;

public class Circle extends Point {

//Declaring instance variables private double radius; //Zero Argumented constructor public Circle() { this.radius=0.0; } //Parameterized constructor public Circle(int x, int y,double radius) { super(x, y); setRadius(radius); } //Getter and Setter methods public double getRadius() { return radius; } public void setRadius(double radius) { if(radius>=0) this.radius = radius; else { System.out.println("Invalid.Radius Must be Positive."); radius=0.0; } } public double calArea() { return Math.PI*getRadius()*getRadius(); } public double calCircum() { return 2*Math.PI*getRadius(); } /* toString() method which displays * the contents of an object inside it */ @Override public String toString() { DecimalFormat df=new DecimalFormat("#.##"); System.out.println(super.toString()); return "Circle# Radius=" + radius + " Area of Circle ="+df.format(calArea()); return " Circle # Radius =" + radius + " Circumference of Circle ="+df.format(calCircum());

}
