What are the access specifiers in Java? List them.

Access specifiers in Java are keywords that define the visibility or accessibility of variables, cl****es, methods and other objects within a Java application. In Java, there are four access specifiers: public, protected (also called package-private), default, and private. https://www.sevenmentor.com/ja....va-training-cl****es

The public is the most permissive. If a cl**** or method is declared public, then it can be accessed by any cl**** within the package, or any package. All cl****es can see and access public members.

The protected specifier restricts the access to members and subcl****es of the same package (regardless package). The protected members are accessible by all subcl****es of the cl**** that declares them, and by cl****es within the same package. This specifier can be used to control access to members of a cl**** within a hierarchy.

The default is also known as package private. It is the absence an access specifier. If a cl**** or method is declared with no access specifiers, then it can only be accessed within the package. Cl****es, methods or variables that have default access will not be visible to any cl****es outside of the package where they were declared.

The private is the most restrictive access specifier. If a cl**** member has been declared private, then it can only be accessed from the cl**** that it was declared in. Private members cannot be accessed from another cl**** or subcl****. This specifier can be used to hide implementation details and enforce encapsulation within a cl****.

These access specifiers enable Java developers to control visibility and accessibility in their code. This promotes encapsulation and information hiding as well as modularity which are all fundamental principles of object oriented programming. Developers can create robust cl****es and APIs by carefully selecting the right access specifiers for each member of the cl****.
