You need to protect your data in Java. This is encapsulation.

Access modifiers control who sees your code.

• Public: Everyone sees it.
• Private: Only the owner class sees it.
• Default: Only the same package sees it.
• Protected: The same package and sub classes see it.

Use getters and setters to manage this.

Example: A gold shop. The gold price is private. A customer uses a getter to see the price. A customer uses a setter to change the price.

You set rules in the setter. You stop people from setting a price too low.

Encapsulation keeps your data safe. It gives you control.
