Access modifiers control who sees your code. They keep your programs safe and organized.

You have four types in Java:

• Public: Access from anywhere.
• Protected: Access within the same package or child classes.
• Default: Access within the same package only.
• Private: Access within the same class only.

Look at this example. You have two packages: salem and madurai.

The Parent class lives in salem. It has a public pin and protected methods.

A Child class in the same package accesses public and protected items.

A Child class in a different package accesses public and protected items through inheritance.

Here is how access works:

• Same class: All modifiers work.
• Same package: Public, protected, and default work.
• Different package (child class): Public and protected work.
• Different package (non-child class): Only public works.
