What are the different types of access modifiers?

Access modifiers are keyWords in programming that define the accessibility of classes, methods, and variables. The main types include public, which allows access from anywhere; private, restricting access to within the same class; protected, permitting access to subclasses and classes in the same package; and default (no modifier), which allows access only within the same package. These modifiers help encapsulate data and control how components of a program interact with each other.
