I love to summarize theoretical concepts in my way. I have made an image to understand access modifiers in java. I hope it can be tagged to your personal notice board.

Some theory:

1. public are accessible everywhere whether same class, sub class, other package etc
2. protected are accessible everywhere in same package. But it becomes private in subclass of another package.
3. default are accessible to the same package whether sub class or independent class.
4. private are accessible to the class itself or its nested class only.
