Super Keyword in java:-

The parent class is also called Superclass in Java and this method is used to access the parent class method.


using this we can call the parent class method from the child class method.

Super is also used in the constructor to call parent class constructor to child class constructor.


Example of Super Keyword in java:-



public class A {
    int a=2;
     void fun()
    {
        System.out.println("A");
    }
}


public class B extends A {
    
    void fun1()
    {
        super.fun();
    }
}



Another Example of Super Keyword in Java:-

class ExamSystem
{
    ExamSystem()
    {
     System.out.println("Default Constructor");
    }  
    ExamSystem(String s)
    {
         this();
        System.out.println("Constructor"+s);
       

    }
    void examDuration()
    {
       System.out.println("3 hours");
    }

    void examContent()
    {
        System.out.println("Exam Content");
    }

    void examPattern() 
    {
        System.out.println("Number System");
    }

}

class ExamSystemNew extends ExamSystem
{
    ExamSystemNew()
    {
        super("super");
        System.out.println("Exam System New Constructor");
    }
    void examPattern() 
    {
        super.examPattern();
        System.out.println("Grade System");
    }


   public static void main(String args[])
   {
       //ExamSystemNew obj = new ExamSystemNew();
      ExamSystem obj = new ExamSystemNew();
     //   ExamSystemNew obj = new ExamSystem();
       obj.examDuration();
       obj.examPattern();
       obj.examContent();

   } 
}
