Create a Java program to simulate the maintenance and repair operations for various types of Star Wars droids. The system will load droid data from a JSON file, perform maintenance based on each droid$$s specific needs, and log repairs.

Define an abstract class $`$Droid$`$ with the following methods:

$$ performMaintenance$()$: Abstract method to be implemented by subclasses specifying maintenance actions based on the droid type.

$$ getStatus$()$: Displays the droid's ID$,$ type, battery level, and repair status.

$$ chargeBattery$()$: Charges the battery to full capacity if it$$s below a specified threshold $($e$.$g$.,25\%).$

Create the following Concrete Classes for Droid Types

$$ AstromechDroid

$$ Implements performMaintenance$()$ with tasks like chargeBattery$()$ and resetting navigation data.

$$ Custom maintenance tasks may include calibrateSensors$()$ for astromech functions.

$$ ProtocolDroid

$$ Implements performMaintenance$()$ with tasks like rechargeBattery$()$ and updateLanguageDatabase$().$

$$ Additional tasks might include polishArmor$()$ for maintaining protocol droid appearances.

$$ BattleDroid

$$ Implements performMaintenance$()$ with tasks like repairWeapons$()$ and reloadAmmo$().$

$$ Custom maintenance includes armor checks and battery recharging for combat readiness.

Exception Handling:

$$ MissingDataException: If any required data field is missing, throw a custom MissingDataException.

$$ InvalidBatteryLevelException: Throw an exception if the battery level is not within $0100.$

$$ UnknownDroidTypeException: If droidType does not match any known type, throw an exception and log the issue.

Each time a performMaintenance$()$ method is called, write an entry to repair$\_$log$.$json.$$ Include repair status and timestamp.$$ Example:

$$ droidID: R$4-$C$2$

$$ droidType: Astromech

$$ status: Maintenance completed

$$ batteryLevel: $100$

$$ repairStatus: Working

$$ timestamp: $2024-11-01$T$14$:$35$:$00$Z

The program should function as follows:

$$ Prompt the user to select a droid by ID$.$

$$ Call the $`$performMaintenance$()`$ method for the selected droid, updating battery level and repair status.

$$ Log maintenance in $`$repair$\_$log$.$json$`.$

$$ After maintenance operations are complete, display a summary of all droids and any still needing repairs.

json file: droids.json
