StarProperties

Instructions

In the following quest, we will work with the same files and classes. You should keep them from one exercise to the following.

Create a file CelestialObject.java.

Create a public class named CelestialObject.
The class must contains four properties :

• x (double)
• y (double)
• z (double)
• name (String)

The (x, y, z) properties are the coordinates of the object.

For the moment, you should declare the properties as public.

Usage

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

public class ExerciseRunner {

    public static void main(String[] args) {
        CelestialObject celestialObject = new CelestialObject();
        System.out.println(celestialObject.x);
        System.out.println(celestialObject.y);
        System.out.println(celestialObject.z);
        System.out.println(celestialObject.name);
    }
}

and its output :

$ javac *.java -d build
$ java -cp build ExerciseRunner 
0.0
0.0
0.0
null
$
