what happens to protected members after inheritance in java?

Question

As in C++ protected members were becoming private in private inheritance . so I am very confused what happens in Java . do here access specifiers remain same or what? like

if suppose below code exists then now shiva will still remain protected inside classB ? can we again use it in classC ?

Any help will be appreciated.

package package1
class classA
{
protected shiva;
}

////////////////////////
import package1
package package2
class classB extends classA
{}

//////////////////////
import package2
class classC extends classB
{}

In java, the inheritance is similar to the C++ public virtual inheritance. So, all access modifiers will remain the same — Sohaib Jundi, Jul 19 '19 at 06:02

Yes, You can use it.

            │ Class │ Package │ Subclass │ Subclass │ World
            │       │         │(same pkg)│(diff pkg)│ 
────────────┼───────┼─────────┼──────────┼──────────┼────────
public      │   +   │    +    │    +     │     +    │   +     
────────────┼───────┼─────────┼──────────┼──────────┼────────
protected   │   +   │    +    │    +     │     +    │         
────────────┼───────┼─────────┼──────────┼──────────┼────────
no modifier │   +   │    +    │    +     │          │    
────────────┼───────┼─────────┼──────────┼──────────┼────────
private     │   +   │         │          │          │    

 + : accessible         blank : not accessible

For more reference, please find the answers to this question here. It seems to me similar.

Yes, you can use the protected field in the subclass.

Protected access modifier lies between the public and default access modifier. It can be accessed outside the package but only through subclasses.

Refer this link for more clarity.

So yes you can use it in the subclasses.
