Definition:
The super keyword enables a subclass to call the methods and fields of its superclass. It is not an instance of the superclass object but a way to tell the compiler which methods or fields to reference. The effect is the same as if the subclass is calling one of its own methods.
Examples:
Consider a subclass Employee that extends its superclass Person:
public class Employee extends Person{
public Employee()
{
//reference the superclass constructor
super();
}
public String getName()
{
//reference superclass behaviors
return super.getFirstName() + " " + super.getLastName();
}
}
The super keyword can be used to reference the constructer of the Person class or any of the behaviors or fields that it has access to (e.g., getFirstName() and getLastName()).
