Justify the output of the code (inheritance/overriding problem)

[pranav thakker]

Hello ranchers,

Can anyone justify the output of following code ?

 
class Parent
 
{
 
             private void method1()
 
            {
 
                        System.out.println("Parent's method1()");
 
            }
 
            public void method2()
 
            {
 
                        System.out.println("Parent's method2()");
 
                        method1();
 
            }
 
}
 
class Child extends Parent
 
{
 
            public void method1()
 
            {
 
                        System.out.println("Child's method1()");                
 
            }
            
 
            public static void main(String args[])
 
            {
 
                       Child c = new Child();
 
                        c.method2();
 

            }
 
}

According to myself output should be as follow :-

Parent's method2()
Child's method1()

Because, we are calling method2 with reference of child class.

But, the actual output is :-


Parent's method2()
Parent's method1()

Please, explain it.

Thanking you all,

Output

Parent's method2()
Parent's method1()

is absolutely correct.

method1 cannot be invoked in polymorphic way because you do not override it. As long as it is marked private it cannot be inherited.
If you would change it to public your output will be as you thought.

private method,method1() in parent class is not overridden by child class.it is another method with the same name

[Balaji Sampath]

If u change the method1() in parents class like:

class Parent{
void method1(){
System.out.println("Parents method1() ");
}
void method2(){
System.out.println("Parents method2() ");
method1();
}
}

then the output would be
Parents method2()
Child method1()

Thanks

But, the actual output is :-
Parent's method2()
Parent's method1()

It's a Child object and a Child declaration, so how is it possible that the output above has "Parent's method1()"?!!
