how to use super class method in java
class Parentclass { //no-arg constructor Parentclass(){ System.out.println("no-arg constructor of parent class"); } //arg or parameterized constructor Parentclass(String str){ System.out.println("parameterized constructor of parent class"); } } class Subclass extends Parentclass { Subclass(){ /* super() must be added to the first statement of constructor * otherwise you will get a compilation error. Another important * point to note is that when we explicitly use super in constructor * the compiler doesn't invoke the parent constructor automatically. */ super("Hahaha"); System.out.println("Constructor of child class"); } void display(){ System.out.println("Hello"); } public static void main(String args[]){ Subclass obj= new Subclass(); obj.display(); } }
