The protected fields or methods cannot be used for classes and Interfaces. A standard design strategy is to make all fields private and provide public getter methods for them. Fields, methods or constructors declared private are strictly controlled, which means they cannot be accesses by anywhere outside the enclosing class. It also cannot be used for fields and methods within an interface.

The private (most restrictive) fields or methods cannot be used for classes and Interfaces. A member has package or default accessibility when no accessibility modifier is specified.įields, methods and constructors declared public (least restrictive) within a public class are visible to any class in the Java program, whether these classes are in the same package or in another package. 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. To take advantage of encapsulation, you should minimize access whenever possible. a class can control what information or data can be accessible by other classes. The access to classes, constructors, methods and fields are regulated using access modifiers i.e.
