Popcorn Hack #1

public class PowerLevelCalculator {
    public static void main(String[] args) {
        int level = 10; // you can change this or take input from user
        double basePower = 100;
        double finalPower = basePower * Math.pow(1.2, level);

        System.out.println("Level: " + level);
        System.out.println("Base Power: " + basePower);
        System.out.println("Final Power: " + finalPower);
    }
}

Level: 10
Base Power: 100
Final Power: 619.17

Popcorn Hack #2

public class LootDropSimulator {
    public static void main(String[] args) {
        // Start the loot drop simulation
        System.out.println("Loot Drop!");

        // Generate a random number from 1–100 to determine item rarity
        int rarityRoll = (int)(Math.random() * 100) + 1;
        System.out.println("Rarity Roll: " + rarityRoll);

        // Declare variables for rarity name and gold value
        String rarity;
        int goldValue;

        // Check the rarity range based on the random roll
        if (rarityRoll <= 60) {
            // 1–60 → Common item
            rarity = "COMMON";
            // Generate gold between 10 and 30 (inclusive)
            goldValue = (int)(Math.random() * (30 - 10 + 1)) + 10;
        } else if (rarityRoll <= 85) {
            rarity = "RARE";
            goldValue = (int)(Math.random() * (70 - 31 + 1)) + 31;
        } else {
            rarity = "LEGENDARY";
            goldValue = (int)(Math.random() * (100 - 71 + 1)) + 71;
        }

        // Display the results of the loot drop
        System.out.println("You got: " + rarity + " item");
        System.out.println("Gold Value: " + goldValue);
    }
}

Loot Drop!
Rarity Roll: 73
You got: RARE item
Gold Value: 54
