Could someone please explain to me the reasoning behind these errors.
As I understand, protected members are accesible to the subclasses in
a different package.

The protected members are accessible, though not
quite in the way you are trying..

See my changes to your second class.

I have the following piece of code -

*******************************************************************************************
1. package MyPack;
2.
3. public class Balance {

...

20. } /*class Balance*/
21.
22. // Subclass of Balance in a different package

package testing;

import MyPack.Balance;

public class TestBalance extends Balance{

    TestBalance(String name, double balance) {
        super(name, balance);
    }

    public static void main(String args[]) {

        TestBalance mybalance = new TestBalance("Someone",1000);
        mybalance.Show();

    }
} /*class TestBalance*/

The code as above should compile cleanly. I am
going to avoid trying to explain further, I'll leave that
to the JLS/OO gurus.
