Class with Instance and Method

Write a program where you have to assign a class called Circle is to be defined as illustrated in the class diagram below. It contains two variables: radius (of type double) and color (of type String); and three methods: getRadius(), getColor(), and getArea().

Three instances of Circles called c1, c2, and c3 shall then be constructed with their respective data members, as shown in the instance diagrams.

Source Code:

package crl;
class circle
{
double radius;
String colour;
circle(double r,String c)
{
radius=r;
colour=c;
}
double getRadius()
{
return radius;
}
String getColour()
{
return colour;
}
double getArea()
{
return 3.1416*radius*radius;
}
}
public class CRL
{
public static void main(String[] args)
{
circle c1=new circle(3.4,"Pink");
circle c2=new circle(1.1,"white");
circle c3=new circle(1.1,"blue");
System.out.println("Radius :"+c1.getRadius() + "Colour :"+c1.getColour()+"Area:"+c1.getArea());
System.out.println("Radius :"+c2.getRadius() + "Colour :"+c2.getColour()+"Area:"+c2.getArea());
System.out.println("Radius :"+c3.getRadius() + "Colour :"+c3.getColour()+"Area:"+c3.getArea());
}
}
