Class Inheritance

Inheritance allows one class (child) to acquire the properties and methods of another class (parent). In Java, we use the 'extends' keyword.

class Vehicle {
    void honk() { System.out.println("Beep!"); }
}
 
class Car extends Vehicle {
    String model = "Mustang";
}

Breakdown

class Vehicle { ... }

The parent class (superclass) with a general method.

class Car extends Vehicle { ... }

The child class (subclass) that inherits everything from Vehicle.

void honk() { ... }

A method defined in the parent class that the Car class can also use.
