Does a class inherit the constructors of its superclass

by

A class does not inherit constructors from any of its superclasses.

In Java, a subclass does not inherit constructors from its superclass in the same way it inherits other members (methods and fields). However, constructors are not inherited explicitly, but they are invoked implicitly when an object of the subclass is created.

Here’s what happens:

  1. When you create an object of a subclass, the constructor of the superclass is invoked first.
  2. If the superclass constructor has parameters, those parameters need to be provided in the subclass constructor using the super keyword.
  3. After the superclass constructor is executed, the subclass constructor is executed.

For example:

java
class Superclass {
public Superclass(int x) {
// constructor logic
}
}

class Subclass extends Superclass {
public Subclass(int x, int y) {
super(x); // invoking superclass constructor
// subclass constructor logic
}
}

// Creating an object of Subclass
Subclass obj = new Subclass(5, 10);

In this example, the Subclass constructor implicitly invokes the Superclass constructor using super(x). While the subclass doesn’t inherit the constructors in the same way it inherits methods and fields, it has a way to call the constructors of its superclass.
