Visibility is another term used for Acess Specifiers for java variables and objects.
One of the techniques in object-oriented programming is encapsulation. It concerns the hiding of data in a class and making them available only through its methods. In this way the chance of making accidental mistakes in changing values is minimized. Java allows you to control access to classes, methods, and fields via so-called access specifiers. The access to classes, constructors, methods and fields are regulated using access modifiers i.e. a class can control what information or data can be accessible by other classes. To take advantage of encapsulation, you should minimize access whenever possible.
Java provides a number of access modifiers to help you set the level of access you want for classes as well as the fields, methods and constructors in your classes. A member has package or default accessibility when no accessibility modifier is specified.
Access Modifiers
1. Private
2. Protected
3. Default
4. Public
Public is the most liberal access specifier and Private is the most restrictive access specifier.
Visibility Control is achieved in Java by using Access Modifiers.
An Access Modifier is a key word in java that determines what level of access or visibility a particular java variable/method or class has. There are 4 basic access modifiers in java. They are:
1. Public
2. Protected
3. Default and
4. Private
Private is the most restrictive access modifier whereas public is the least restrictive. Default is the access protection you get when you do not specifically mention an access modifier to be used for a java object.
