Final Assignment $(85$ points$)$

Please complete the code to satisfy the following requirements:

Create an interface Inhabitable that has one method lifeForm$()$ that returns void.

Create an abstract CelestialObject class that implements Inhabitable and has an attribute celestialObjectType of type String. The celestialObjectType is set through the constructor. Provide the get for the attribute.

The lifeForm$()$ method will print a trace message in this format: $$name of the current class $$ name of the current method $$ your last name$.$ Replace the class and the method with the actual class and method and name where you print the trace. For example: $$classA $$ function$1$ Romano$$

Create a Planet class that extends CelestialObject class and has the following attributes: planetName $$ string, numberOfMoons $$ integer, PlanetType that can be $$terrestrial$$ or $$Jovian$,$ celestialObjectType should be hardcoded as the string $$planet$.$

Provide a constructor for the Planet class, that takes the $3$ parameters: planet name, number of moons and type.

Validate the parameters:

$$ If the planetName or the planetType is missing throw an InvalidArgumentException.

$$ If the planetName attribute length is more than $30$ char throw an $$InvalidPlanetNameException$$ checked exception $$ create exception class.

$$ If the planetMoons attribute value is more than $200$ throw an $$InvalidNumberOfMoonsException$$ unchecked exception $$ create exception class.

$$ If the planetType is not $$terrestrial$$ or $$Jovian$$ throw an $$InvalidPlanetTypeException$$ unchecked exception $$ create exception class.

The checked exception should be thrown all the way to main$().$

For the Planet class:

$$ Create the $$gets$$ and the $$sets$$ for the $3$ attributes.

$$ Set the numbers and constants for validations in a static initializer block.

$$ Override equals$()$ to compare two planet instances, based on the name, moons and type.

$$ Override the associated function for equals$().$

$$ Override ToString$()$ to display the class data in the format $$NAME $$ type $$ moons$.$ Example: $$EARTH $$ terrestrial $0$ moons$.$ Note the name is capitalized.

Create a Singleton Planets class that would always return the same instance of the Planets class. It will also return the same List of Planets.

Create a PlanetsMain class with a main$()$ that would call the following functions to display the results.

In PlanetsMain, create the following methods using Stream:

Method name

Return

Resulting behavior

printAllPlanetsByName

none

List of Planet information

$$EARTH $$ terrestrial $0$ moons$$

Capitalize the Name

Prints all planet information sorted by the name ascending. Format to output:

List of planets sorted by Name

$=========================$

$$EARTH $$ terrestrial $0$ moons$$

$...$

printAllPlanetsByMoons

none

List of Planet information

$$EARTH $$ terrestrial $0$ moons$$

Capitalize the Name

Prints all planet information sorted by the number of moons descending. Format to output:

List of planets sorted by Moons

$=========================$

$$EARTH $$ terrestrial $0$ moons$$

$...$

printPlanetsByType

planetType

List of Planets of the required type

Prints the planets of the type provided. If the type is $$terrestrial$$ print:

Terrestrial planets

$==============$

Planet$1$

$...$

printPlanetMaxMoons

none

Name of planet and no of moons

Prints the info for the planet with the most moons

$$EARTH $$ terrestrial $0$ moons$$

In main$()$:

$1.$ Print your name and student number.

$2.$ Print how many planets are in the list.

$3.$ Print the list of planets sorted by name, with title.

$4.$ Print the list of planets sorted by the number of moons descending, with title.

$5.$ Print the list of the terrestrial planets, with title.

$6.$ Print the list of the Jovian planets, with title.

$7.$ Trigger the $3$ types of errors and print a message to prove.

Format your output for readability. Leave one empty line between the sections. Start the section with the title. For example:

Create Unit Tests for the first two methods. Save the unit tests in a $$tests$$ package marked for tests $$ should be green.

Create the UML class diagram for the requirements and upload it as pdf $$ Optional $5$p
