Question

Suppose you implement a class, but you do not write a constructor. What kind of constructor does Java usually provide automatically?

Answer 1

If a class in Java does not have a constructor defined, Java provides a default no-argument constructor that calls the superclass's constructor.

Step-by-step explanation:

When you implement a class in Java without writing a constructor, Java automatically provides a default constructor for that class. This default constructor is a no-argument constructor which does nothing but call the superclass's no-argument constructor. If the class does not explicitly extend another class, it implicitly extends the Object class, and the default constructor will call the constructor of the Object class. The purpose of this constructor is to ensure that the class can be instantiated with default values for its instance variables.
