What are access specifiers and access modifiers in Java?
There is a scenario where I am designing a system where I have multiple classes that can interact with each other. Explain to me how can I use access specifiers and modifiers for controlling the visibility and accessibility of a wide range of class members, methods, and even fields in my system for ensuring encapsulation, security, and maintainability.
In the context of Java programming language the access specifiers and access modifiers in Java are keywords which is used in defining the accessibility, and visibility of classes, methods, and even variables in your particular program.
There are four access specifiers in Java programming language which are given below:-
Public
The members when declared as “public” then it would be accessible from any class.
Public class MyClass {
Public int publicVariable;
Public void publicMethod() {
// Method logic here
}
}Private
The members when declared as “public” then it would be accessible within the same class.
Public class MyClass {
Private int privateVariable;
Private void privateMethod() {
// Method logic here
}
}Protected
Tge members when declared as “protected” then it would be accessible within the same subclass.
Public class MyClass {
Protected int protectedVariable;
Protected void protectedMethod() {
// Method logic here
}
}Default
If there is no accessible then there are “default” access specifiers in Java programming language.
Class MyClass {
Int defaultVariable;
Void defaultMethod() {
// Method logic here
}
}
