• Try to use only the information given up to this point in this book.
• Try not to give up until you've given it a solid attempt

Challenge 1

Write a method named anothaOne. Each time this method is called it should return a number one larger than the last time it was called.

anothaOne should take no arguments.

// CODE HERE

int anothaOne() {
    // CODE HERE
}

void main() {
    IO.println(anothaOne()); // 1
    IO.println(anothaOne()); // 2
    IO.println(anothaOne()); // 3
    IO.println(anothaOne()); // 4
    IO.println(anothaOne()); // 5
}

Challenge 2

Make a class named DJKhaled. If you ask DJ Khaled to produceMusic some lyrics should be printed out but also anothaOne should be called at least 7 times.¹

// CODE FROM LAST SECTION

class DJKhaled {
    void produceMusic() {
        // CODE HERE
    }
}

void main() {
    IO.println(anothaOne()); // 1
    var dj = new DJKhaled();
    dj.produceMusic();
    IO.println(anothaOne()); // 8+, at least
}

Challenge 3

Make a method named nextLyric. It should take no arguments and return a String. Each time it is called it should return a subsequent line from Kendrick Lamar's 2025 Superbowl Halftime Show.

You should be able to find a transcription of the lyrics here.

Once all the lyrics are exhausted nextLyric should start returning null.

// CODE HERE

String nextLyric() {
    // CODE HERE
}

void main() {
    for (
        String lyric = nextLyric(); 
        lyric != null; 
        lyric = nextLyric()
    ) {
        IO.println(lyric);
    }
}
