The following code example illustrates how we can implement multiple inheritance in PHP using traits. <?php// trait 1trait t1 { public function sayhello() { echo "Hello! Welcome to"; } } // trait 2trait t2 { public function sayfor() { echo " Intellipaat."; } } class Child { use...
Why does the following code display "New A New B"? class A { public A() { System.out.println("New A"); } } class B extends A { publ
The following code example shows how to use inheritance to create a simple WMI event hierarchy using theBaseEventhelper class. The top-level managed event class,TopEvent, is represented by a WMI class,TopEvent, derived from__ExtrinsicEvent. TheTopEventclass will have two children, Branch1Event...
A call to inheritPrototype() can replace the subtype prototype assignment in the previous example, as shown here: View Code This example is more efficient in that the SuperType constructor is being called only one time, avoiding having unneccessary and unused properties on SubType.prototype. Furthe...
Example Add the __init__() function to the Student class: class Student(Person): def __init__(self, fname, lname): #add properties etc. When you add the __init__() function, the child class will no longer inherit the parent's __init__() function....

This is what theCar‘s implementation of theVehicleinterface would look like! For this example, I've stated (in code) that aCarhas 5 seats, 4 wheels and 2 doors. Let's see what aBuswould look like: public class Bus implements Vehicle { @Override public Integer getNumberOfSeats() { ret...
So, let us understand how this code works: When you create an object of the child class (Car), it has the attributes and methods of the parent class (Vehicle) and its unique features. In this example, myCar is an object of the Car class. It inherits attributes and methods from the ...
