🎧 Day 5 — MoodPlay | #30Days30Projects

On Day 5 of my #30DaysJavaCLI challenge, I wanted to combine something fun and personal with my learning: music and mood. So I built MoodPlay, a Java CLI app that recommends Hindi and Marathi songs based on the user’s current mood.

This project helped me strengthen my knowledge of:

• Enums

• Switch statements

• ArrayLists

• Randomization

• Console styling for better UX

Let’s dive into it.

🧠 Project Idea

The idea is simple but meaningful:

Ask the user about their mood (like happy, sad, energetic, romantic), and suggest a list of 3 random songs from a preset list tailored to that emotion.

🧩 Code: MoodPlay.java

package src;

import java.util.*;

public class MoodPlay {

    enum Mood {
        HAPPY, SAD, ENERGETIC, ROMANTIC
    }

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        printBanner();

        System.out.println("\u001B[34mWhat's your current mood?\u001B[0m");
        System.out.println("Options: Happy, Sad, Energetic, Romantic");

        String userInput = sc.nextLine().trim().toUpperCase();

        try {
            Mood mood = Mood.valueOf(userInput);
            suggestSongs(mood);
        } catch (IllegalArgumentException e) {
            System.out.println("\u001B[31mOops! Invalid mood entered. Please try again.\u001B[0m");
        }

        sc.close();
    }

    private static void suggestSongs(Mood mood) {
        Map<Mood, List<String>> moodSongs = new HashMap<>();

        moodSongs.put(Mood.HAPPY, Arrays.asList(
                "Zhingaat – Sairat",
                "Gallan Goodiyan – Dil Dhadakne Do",
                "Kar Gayi Chull – Kapoor & Sons",

        ));

        moodSongs.put(Mood.SAD, Arrays.asList(
                "Channa Mereya – Ae Dil Hai Mushkil",
                "Agar Tum Saath Ho – Tamasha",
                "Kadhi Tu – Timepass",
                "Tadap Tadap – Hum Dil De Chuke Sanam",
                "Apna Time Aayega (Slow version)",
                "Mala Ved Lagale Premache – Timepass"
        ));

        moodSongs.put(Mood.ROMANTIC, Arrays.asList(
                "Tum Hi Ho – Aashiqui 2",
                "Tujh Mein Rab Dikhta Hai – Rab Ne Bana Di Jodi",
                "Satrangi Re – Dil Se",
                "Pehli Nazar – Race",
                "Jeene Laga Hoon – Ramaiya Vastavaiya",
                "Man Udhaan Varyache – Agga Bai Arrecha!"
        ));

        moodSongs.put(Mood.ENERGETIC, Arrays.asList(
                "Bhaag DK Bose – Delhi Belly",
                "Zinda – Bhaag Milkha Bhaag",
                "Malhari – Bajirao Mastani",
                "Aala Holicha San – Jatra",
                "Apna Time Aayega – Gully Boy",
                "Sher Aaya Sher – Gully Boy"
        ));

        List<String> songs = moodSongs.get(mood);
        Collections.shuffle(songs);

        System.out.println("\n\u001B[32m🎵 Here are some " + mood.name().toLowerCase() + " songs for you:\u001B[0m");

        for (int i = 0; i < 3; i++) {
            System.out.println("  ➤ " + songs.get(i));
        }

        System.out.println("\n\u001B[35mEnjoy your vibe! 🎧\u001B[0m");
    }

    private static void printBanner() {
        System.out.println("\u001B[36m===============================");
        System.out.println("       Welcome to MoodPlay       ");
        System.out.println("===============================\u001B[0m");
    }
}

🔍 What I Learned

• How Enum makes handling predefined categories like moods clean and error-proof.

• Mapping moods to songs using HashMap.

• Styling terminal output with ANSI escape codes to make Java CLI more visually appealing.

• Using Collections.shuffle() to randomize recommendations for freshness.

---

✅ What's Next?

For future improvements, I might:

• Integrate an actual API like Spotify or YouTube to play the songs.

• Add a GUI using Java Swing.

• Let users save their favorite tracks to a local file.
