Create a subclass named Square from the superclass GeometricObject. Create an instance variable named width with initial value 0. Create a no-arg constructor. Create the another constructor, which has one parameter named wid. Assign the wid to the instance variable named width. Create the getWidth() method, the setWidth() method. Override the getArea() method. Override the getPerimeter() method. Create a test class named Test to create an instance with wid= 6 from Square class. Call the getArea() and getPermeter() methods to print out the area and perimeter of the square with width=6.

```
**Explanation:**
This code defines an abstract class named `GeometricObject`, which serves as a blueprint for geometric shapes, providing common properties and methods related to them:
- **Fields:**
- `color`: A `String` representing the color of the geometric object, initialized to "white".
- `filled`: A `boolean` indicating whether the object is filled.
- `dateCreated`: A `java.util.Date` object holding the date the object was created.
- **Constructors:**
- A no-argument constructor initializes `dateCreated` to the current date.
- A parameterized constructor accepts `color` and `filled` values, also initializing `dateCreated` to the current date.
- **Accessors & Mutators:**
- `getColor` and `setColor`: Access and modify the `color` field.
- `isFilled` and `setFilled`: Access and modify the `filled` field.
- `getDateCreated`: Returns the `dateCreated` field.
- **Methods:**
- `toString`: Overrides the default `toString` method to provide a string representation of
