It is called Math.pow(). Since this is exercise, please don’t use it and try to implement the exercise manually with a for loop. Write a method that calculates the area of a circle, given its radius. Search on Google, if you need the formula. Use the double type, not int, for both parameter and return value. You’ll need the constant π, the Greek Pi, that is approximately 3.14. It’s better to use the Java constant Math.PI instead of typing directly 3.14 in the code.

This first exercise shall lead you through all the basic concepts in OOP. A class called circle is designed as shown in the following class diagram. It contains: Two private instance variables: radius (of the type double) and color (of the type String), with default value of 1.0 and "red", respectively. Two overloaded constructors - a default constructor with no argument, and a constructor which takes a double argument for radius. Two public methods: getRadius() and getArea(), which return the radius and area of this instance, respectively.
