Call Super-class Constructor from Child Class Constructor in Java

class CallConstructor {

    // constructor of the superclass
    CallConstructor (int number1, int number2) {
        if (number1 > number2) {
            System.out.println("The greater number is: " + number1);
        }
        else {
            System.out.println("The greater number is: " + number2);
        }
    }
}

    // child class
    public class Child extends CallConstructor {
        
    // constructor
    Child() {
       
        // calling super class’s constructor
        super(29, 16);
    }

     // main method
     public static void main(String[] args) 

        // calling child class constructor
        Child obj = new Child();
    }
}

The greater number is: 29

• This program is used to call the constructor of the superclass through the constructor of the child class.
• A super class CallConstructor  is created that holds the parameters as (int number1, int number2) and finds the latest version through if…else statement.
• Another class, subclass Child is created that calls the constructor of the superclass from its constructor using super(29, 16).
• By creating an object in the main method , the superclass constructor CallConstructor(int number1, int number2) is called from the subclass constructor and the latest version is printed on the screen.
