Is it possible to override a private method of a parent class?

Private methods in classes are usually not accessible for overriding in child classes because they are hidden from subclasses. In languages that support access modifiers (such as Java, C#), private methods belong only to the class itself and are not visible in subclasses, so they cannot be overridden.

If you need to change the behavior of a method in a subclass, you typically make the method protected or public so it can be overridden. In some languages (like Python), privacy is implemented by convention, and methods with "private" names can be overridden, but this is not recommended.

Example in Java:

class Parent {
    private void secret() {
        System.out.println("Parent secret");
    }
    public void callSecret() {
        secret();
    }
}

class Child extends Parent {
    // This is not an override, but a new function
    private void secret() {
        System.out.println("Child secret");
    }
}

Calling callSecret() on a Child object will invoke the secret() method from Parent, not from Child.
