### 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 :
|
||
|
|
|
||
|
|
```java
|
||
|
|
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 :
|
||
|
|
```shell
|
||
|
|
$ javac *.java -d build
|
||
|
|
$ java -cp build ExerciseRunner
