Why is allowed for an abstract class to have concrete private instance methods?

Here are some questions that you should consider:
What do you think is the relation between the two things? Why do you think it should not be allowed?
What is the purpose of an abstract class? What is the purpose of a private instance method?

I have found a use case for the private method:
Code: Select all
public class TestClass{
abstract class Cc{
private void whap(){};
public void doSomething(){ whap(); };
}
public static void main(String args[]){
}
}
