Protected member difference in Java and c#

Question

I have the following code in Java

public class First {
    protected int z;

    First()
    {
        System.out.append("First const");
    }

}

class Second extends First {

    private int b;
    protected int a;

}

class Test {
    /**
     * @param args the command line arguments
     */
    int a=0;

    public static void main(String[] args) {
        // TODO code application logic here
        First t=new Second();
        t.z=10; work fine
        First x=new First();
        x.z=1; // works fine
    }
}

so I can access z by creating object of base class

C#

class A
{
    protected int x = 123;
}

class B : A
{
    static void Main()
    {
        A a = new A();
        B b = new B();

        // Error CS1540, because x can only be accessed by 
        // classes derived from A. 
        // a.x = 10;  

        // OK, because this class derives from A.
        b.x = 10;
    }
}

So i cannot access a, if through base class object. I found Java and C# similar from an OOP point of view, is there any difference between both languages for protected members?

with reference to this doc

Answer 1

The difference is that in java a protected member can be accessed from the same package. In C++ there is no equivalence for package level visibility in java.
