//There are 4 rules that we must follow to override a method

/*Overriding Rule.1->

* We can not reduce the visibility of overridden method but we can increase the visibility of overridden method

*/

//Example 1->

class Demo1

{

public void disp()

{

System.out.println("Parent");

}

}

class Demo2 extends Demo1

{

// void disp() //Here we get the error because by default the access modifier is default

// { // and we know that the visibility of default is less then public hence we got the error coz this is not allowed

// System.out.println("Child");

// }

}

//Example 2->

class Demoo1

{

void disp()

{

System.out.println("Parent");

}

}

class Demoo2 extends Demoo1

{

public void disp() // here we will not get any error because the parent class disp() access modifier is default

{ // and this overridden method access modifier is public it means here we increase the visibility and this is allowed

System.out.println("Child");

}

public static void main(String[] args) {
