it fixes the issue

wish of those help The short answer is that you can only override methods that are visible. The first two methods, pri and pac are private and package protected respectively. Because nothing outside the class can see a private method, it can't be overridden. Similarly because Concrete1 is in a different package from Base it can't see Base.pac so cannot override it.
What this means is that while you define a pri and pac method in Concrete1, they're just methods that happen to have the same name as the methods in Base, not overrides. The other two methods pro and pub are protected and public respectively, so are visible to Concrete1. As a result the pro and pub methods in Concrete1 are overrides of the methods of the same name in Base.

I hope this helps . The keyword super gives you access to (visible) members of the superclass. So, you could call the print() method of the superclass, and then just do the specific work of the subclass:
code :
public void print() {
    super.print();
    System.out.println ("GPA: " + gpa);
}
public void print() {
    print();
    System.out.println ("GPA: " + gpa);
}

To fix this issue Privare methods cannot be overriden. You can write the method in child but practically it is not overriding
From the Java language specification JLS.

it helps some times In the first case son.printMe() calls Son's printMe() (since Son overrides that method), which calls Dad's getMe() (since Son didn't override that method), which returns "dad".
In the second case son.printMe() calls Dad's printMe() (since Son didn't override that method), which calls Son's getMe(), since Son overrides that method. Therefore "son" is printed.
