class Vehicle {
  protected String brand = "Ford";        // Vehicle attribute
  public void honk() {                    // Vehicle method
    System.out.println("Tuut, tuut!");
  }
}

class Car extends Vehicle {
  private String modelName = "Mustang";    // Car attribute
  public static void main(String[] args) {

    // Create a myCar object
    Car myCar = new Car();

    // Call the honk() method (from the Vehicle class) on the myCar object
    myCar.honk();

    // Display the value of the brand attribute (from the Vehicle class) and the value of the modelName from the Car class
    System.out.println(myCar.brand + " " + myCar.modelName);
  }

Inheritance in Java is a mechanism in which one object acquires 
all the properties and behaviors of a parent object.
It is an important part of OOPs (Object Oriented programming system).

Vererbung in Java

Java Inheritance (Subclass and Superclass)
In Java, it is possible to inherit attributes and methods from one class to another. We group the "inheritance concept" into two categories:

subclass (child) - the class that inherits from another class
superclass (parent) - the class being inherited from
To inherit from a class, use the extends keyword.

Beispiel für Java -Vererbung

public class Parent
{
  //methods and constructors 
}

public class Child extends Parent
{
	//inherits methods from Parent class
}
