Can a class be both abstract and final in Java? 🤔

⚠️ The answer is No!

abstract → class is incomplete, must be extended.

final → class cannot be extended.
❌ These are opposite concepts, so combining them is not allowed.

📌 Example:

// ❌ Invalid: Abstract + Final
// abstract final class Test {} // Compilation error

// ✅ Valid: Abstract class
abstract class Animal {
abstract void sound();
}

// ✅ Valid: Final class
final class Utility {
void show() {
System.out.println("This is a final class");
}
}
