Lesson: 14 | Using the super Keyword

The super keyword can be used by classes that are extended from virtual or abstract classes. By using super, you can override constructors and methods from the parent class.

Main Class| ClassA

public virtual class ClassA {
    public String myFirstName;
    public String myLastName;

    public ClassA() {

        myFirstName = 'Engin';
        myLastName = 'Basturk';
    }

    public ClassA(String firstName, String lastName) {

        myFirstName = firstName;
        myLastName = lastName;
    }

    public virtual void printName() {

        System.debug('My name is ' +  myLastName);
    }

   public virtual String getFirstName() {
       return myFirstName;
   }
}

Sub Class| ClassB

You can create ClassB that extends ClassA

public class ClassB extends ClassA {
  public override void printName() {
        super.printName();
        System.debug('But you can call me ' + super.getFirstName());
    }
}

Apex Code

ClassB obj =new ClassB();
obj.printName();
