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());
}
}

    MAIN CLASS:


    package CircleCode;

    public class Circle {

    public static void main(String[] args) {


    ColorCode C1;
    ColorCode C2;
    ColorCode C3;


    C1=new ColorCode("Blue",2);
    System.out.println("--------Properties of Circle C1-----");
    C1.printInfo();
    System.out.println("\n\n");
    System.out.println("--------Properties of Circle C2-----");
    C2=new ColorCode("Red",2);
    C2.printInfo();
    System.out.println("\n\n");
    System.out.println("--------Properties of Circle C3-----");
    C3=new ColorCode("Red",1);
    C3.printInfo();

    }


    Helping Class :

    package CircleCode;
    public class ColorCode {

    private double radius;
    private String color;
    public double pi=3.1416;

    public ColorCode(){

    radius=0;
    color=new String();
    }

    public ColorCode(String color){
    radius=0;
    color=new String(color);

    }

    public ColorCode(String color,double radius){
    this.color=color;
    this.radius=radius;
    }

    public double getRadius(){
    return radius;
    }

    public String getColor(){
    return color;
    }

    public double getArea(){
    return pi*radius*radius;
    }

    public void printInfo(){

    System.out.println("Radius: "+getRadius());
    System.out.println("Color: "+getColor());
    System.out.println("Area: "+getArea());
    }
    }



    }
