🔑 Boolean Hacks in Java: Whack-A-Mole

This notebook has short Boolean challenges. Edit the code where it says TODO to make it work.

Challenge 1: Mole Hit

Set hit to true if the player hits the mole. Print “Hit!” if hit is true, otherwise print “Miss!”.

let hit = false; // Change to true if you hit the mole

// TODO: check if hit is true
if (hit) {
    console.log("Hit!");
} else {
    console.log("Miss!");
}

Challenge 2: Out of Lives

Each time the player misses a mole, they lose a life. If lives reach 0, print “Game Over!”.

let lives = 3; // Decrease when a mole is missed
let missed = true; // Change to true if player misses a mole

// TODO: decrease lives when a mole is missed
if (missed) {
    lives -= 1;
}

if (lives === 0) {
    console.log("Game Over!");
} else {
    console.log("Keep playing! Lives left: " + lives);
}

Challenge 3: High Score Boost

If the player’s score reaches 10 or more, give them a bonus of +5 points.

let score = 8; // Increase when a mole is hit

// TODO: add 5 bonus points when score is 10 or higher
if (score >= 10) {
    score += 5;
    console.log("New High Score! Bonus awarded.");
} else {
    console.log("Try again!");
}

console.log("Final score: " + score);

Challenge 4: Bonus Mole Condition

A golden mole should only give a bonus if both goldenMole and hit are true. Fix the condition.

let goldenMole = true;   // Special mole appears
let hit = true;          // Change to true if the mole is hit

// TODO: fix the condition so bonus only happens when BOTH are true
if (goldenMole || hit) { // <-- wrong condition
    console.log("Bonus!");
} else {
    console.log("No bonus.");
}
