Can abstract class have a constructor in Java? 🤔

✅ Yes, abstract classes can have constructors.
👉 They are used to initialize common fields or resources.
⚠️ But you cannot create objects of an abstract class directly.
✅ The constructor runs when a child class object is created.

📌 Example:

abstract class Animal {
Animal() { System.out.println("Animal constructor called"); }
}
class Dog extends Animal {
Dog() { super(); System.out.println("Dog constructor called"); }
}
public class Test {
public static void main(String[] args) {
Dog d = new Dog();
}
}


💡 Output:

Animal constructor called
Dog constructor called
