Popcorn Hack #1: Power Level Calculator

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        
        int base = 100;
        
        // Get user input to determine level
        System.out.print("Enter the level: ");
        int level = scanner.nextInt();
        System.out.print("");

        // Calculate final power based off base and level
        double finalPower = base * Math.pow(1.2, level);

   
        // Print variables
        System.out.printf("Level: %d\n", level);
        System.out.printf("Base Power: %d\n", base);
        System.out.printf("Final Power: %,.2f\n", finalPower);

        scanner.close();
    }
}


Main.main(null);

Enter the level: Level: 2
Base Power: 100
Final Power: 144.00

        int gold = 0;
        String rarityCategory;

        // Store a random number 1-100
        double rarityNumber = (int)(Math.random() * 100) + 1;

        // Assign rarity category based off random number
        if (rarityNumber < 60) {
            rarityCategory = "Common";

        }
        
        // Print item that was retrieved and its value
        System.out.println("Loot Drop!");
        System.out.printf("You got: %s item\n", rarityCategory.toUpperCase());
        System.out.printf("Gold value: %d\n", gold);
    }
}

Main.main(null);

Loot Drop!
You got: LEGENDARY item
Gold value: 86
