Question #263393
class MyClassCircle {
private double radius;
MyClassCircle(double radius) {
this.radius = radius;
}
public double getArea() {
return Math.PI * radius * radius;
}
}
class GetAreaDemo {
public static void main(String [] args) {
MyClassCircle circle = new MyClassCircle(5.6);
System.out.println("Area of the circle with radius 5.6 equal to " + cicle.getArea());
}
}
