# 🚀Doctor Strange's Guide to Collections in Java🧙‍♂️✨

***<mark>Greetings, fellow coders! </mark>*** 🚀

Today, we're diving into the mystical realm of Java Collections Framework, guided by none other than the Sorcerer Supreme himself, Doctor Strange!

🌀 Let's explore List, Set, and Map through the enchanting world of spells, artifacts, and portals.

👨‍💻 Ready to cast some coding magic? 🌟

### **<mark>🔮 Library of Spells</mark>**

List Imagine having access to the Sanctum Sanctorum's library filled with ancient and powerful spells!

📚 In Java, we can use a List to store these spells. Lists maintain the order of insertion and allow duplicates, making them perfect for our spell collection.

📋 Lists are great for keeping things in order, just like how Doctor Strange meticulously organizes his Spell-Book! 🪄

---

### <mark>🏺Artifacts of the Sanctum Sanctorum</mark>

Set Next, let's look at the unique and powerful artifacts housed in the Sanctum Sanctorum.

🏺 To ensure no duplicates, we use a Set. Sets are perfect for collections where each item must be unique.

🔗 Sets ensure that each artifact is one-of-a-kind, just like the mystical items Doctor Strange relies on! 🔮

---

### <mark>🌌 Portal Coordinates</mark>💫

Map Lastly, let's navigate through the multiverse using portals!

🌌 A Map is perfect for storing portal coordinates, mapping dimension names to their specific locations.

🗺️ Maps are ideal for handling key-value pairs, ensuring Doctor Strange can always find his way through the multiverse! 🌠

---

### ✨ Bonus:

Sorting the Collections! Just like organizing spells and artifacts, sorting can be magical too!

🧹 Using Collections.sort(), we can keep our lists neat and ready for any adventure.

🔮 Sorting helps keep our collections organized, ready to face any mystical threat that comes our way! 🧙‍♂️📜

Embrace the magic of Java Collections and may your code be as powerful as the Sorcerer Supreme! 💻🔮

System.out.println("\\nArtifacts in the Sanctum Sanctorum:");

System.out.println(artifact);

}

// Map - Portal coordinates to different dimensions

Map&lt;String, String&gt; portals = new HashMap&lt;&gt;();

portals.put("Dark Dimension", "13°N, 77°E");

portals.put("Mirror Dimension", "23°S, 45°W");

portals.put("Astral Dimension", "0°, 0°");

portals.put("Dark Dimension", "14°N, 76°E"); // Overwriting previous entry

System.out.println("\\nPortal Coordinates:");

for (Map.Entry&lt;String, String&gt; portal : portals.entrySet()) {

System.out.println(portal.getKey() + ": " + portal.getValue());

}

// Extra - Using Collections methods

Collections.sort(spells);

System.out.println("\\nSorted Library of Spells:");

for (String spell : spells) {

System.out.println(spell);

}

List sortedArtifacts = new ArrayList&lt;&gt;(artifacts);

Collections.sort(sortedArtifacts);

System.out.println("\\nSorted Artifacts in the Sanctum Sanctorum:");

for (String artifact : sortedArtifacts) { System.out.println(artifact);

}

}

}

Happy coding, fellow sorcerers! 🧙‍♂️✨
