[Solved] private member cannot accessible in child class but my below code give successful run why [closed]

Question

In your code you are setting name as private String :

 private String Name;

and accessing it using a public function getName() and returning its value to the caller:

 public String  getName()
    {
        return Name;
    }

and as your (getter) function getName() has a public access modifier you can
call it using child class object:

 childClass c=new childClass();
    c.display("Hazrat Ali");
    System.out.println("My father name is:"+c.getName());

Encapsulation / Data hiding

To achieve encapsulation in Java −

Declare the variables of a class as private.
Provide public setter and getter methods to modify and view the variables
values.

Benefits of Encapsulation

The fields of a class can be made read-only or write-only.
A class can have total control over what is stored in its fields.
Encapsulation provide control over the data.
