Hi Friend,
Try the following code:
import java.util.*;
class Circle{
double radius;
Circle(){
}
Circle(double radius){
this.radius=radius;
}
public double getRadius(){
return radius;
}
public boolean equals(Circle c) {
if (c.getRadius() == this.getRadius()){
return true;
}
else{
return false;
}
}
}
public class CircleApplication
{
public static void main(String[] args)
{
Scanner input=new Scanner(System.in);
System.out.print("Enter Radius1: ");
double r1=input.nextDouble();
Circle c1=new Circle(r1);
System.out.print("Enter Radius2: ");
double r2=input.nextDouble();
Circle c2=new Circle(r2);
boolean result=c1.equals(c2);
System.out.println(result);
}
}
Thanks
