StarInheritance

Instructions

Create a new class Star in a file named Star.java.

This class inherits from CelestialObject. We add a private double property magnitude, with public getter and setter.

Usage

Here is a possible ExerciseRunner.java to test your function :

public class ExerciseRunner {

    public static void main(String[] args) {
        Star star = new Star();
        
        System.out.println(star.getName());
        System.out.println(star.getX());
        System.out.println(star.getY());
        System.out.println(star.getZ());
        System.out.println(star.getMagnitude());
    }
}

and its output :

$ javac *.java -d build
$ java -cp build ExerciseRunner
