![]() The output of this program will be: Mammals can eatĪs we discussed the final keyword would help in not inheriting the properties. It should be the first statement inside any constructor. In case we don’t wish to inherit the properties of the super class, we can use final keyword.īelow is a program for better understanding of how super class can be invoked using parent class method: class Mammals super() and this(): super() and this() are used to call the constructor of the parent class and current class respectively.The keyword will override all the properties of the parent class.Syntax super ( arguments ) // calls the parent constructor (only inside the constructor) super. The super() method should be invoked initially in the child class constructor. ES6 (JavaScript 2015) is supported in all modern browsers: super is not supported in Internet Explorer 11 (or earlier). ![]() Super is referencing to the extended class. If youd like to learn more about Object, you can read the source code of Object.java here. In your case, super is calling the default constructor of Object. Using it with constructors: super keyword can access both the parametric as well as non- parametric constructors of the parent class. Additionally, if the author of a class doesnt create a constructor for the class, a default constructor is created that does nothing.As parent and child class will have the same data members, super will remove the ambiguity in that case. ![]()
