Overview

In this tutorial, we will learn about super keyword in Java. In the previous post, we  have learnt about this keyword.

https://www.testingdocs.com/java-this-keyword-with-example/

super is a reference variable that points to the super class object. We can use this keyword in sub class to refer to the parent methods, variables and constructors.

Example

package staff;

// Constructor
public class SalaryEmployee extends Staff {
 private double empSalary;

 //Constructor
 public SalaryEmployee(String name, String address,double salary) {
 super(name, address);
 this.empSalary = salary;
 }

}

Notice how we have invoked Parent class constructor using the super keyword.

super(name, address);
