The access level refers to the visibility or accessibility of a variable, class, or method in object-oriented programming. It determines which parts of the code can access and manipulate these elements.
Think of access levels like different areas within a school building. Some areas are open to everyone (public), some are restricted to specific groups (protected), and some are only accessible by one person (private).
Public: This access level allows variables, classes, or methods to be accessed from anywhere in the program.
Protected: This access level makes variables, classes, or methods accessible within their own class and any subclasses.
Private: This access level restricts variables, classes, or methods to be accessed only within their own class.
