Are the private variables and private methods of a parent class inherited by the child class in Java?
No, a child class can’t inherit private members of the parent class, it can inherit only protected, default, and public members of it. If you try it gives you a compile time error as: −
Example
class Super{ private int data = 30; public void display(){ System.out.println("Hello this is the method of the super class"); } } public class Sub extends Super{ public void greet(){ System.out.println("Hello this is the method of the sub class"); } public static void main(String args[]){ Sub obj = new Sub(); System.out.println(obj.data); } }
On executing this example it will give an compiletime error as shown below −
Exception in thread "main" java.lang.Error: Unresolved compilation problem: The field Super.data is not visible at Sub.main(Sub.java:13)
