Introduction:<\/h1>\n

In Java, we have to deal with classes, methods, variables, etc. Let’s suppose we have a class and we need to use variables or methods in different classes\/packages. OR we want to specify that a variable or method will be accessed within a defined area. To manage the accessibility of any variables, methods, or classes\/packages we use Access Modifiers. In one word, Access Modifiers are responsible for managing the scope of variables, methods, etc.<\/p>\n

\"\"<\/p>\n

In the above figure, we can see that each variable has its own scope of access within or outside the class.<\/p>\n

Access Modifier Types:<\/h1>\n

There are mainly 4 types of access modifiers available in java. These are the kind of keyword that is used to define the scope or accessibility within or outside.<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Default Access Modifier:<\/h2>\n

The Scope of the default modifier always deals inside the package.<\/p>\n

If we don’t specify any scope for variables, methods, or classes then it automatically considers it a Default access modifier.<\/p>\n

\"\"<\/p>\n

Public Access modifier:<\/h2>\n

Public access modifier can be used globally i.e. it can be accessible inside a package as well as another package also. We can specify the scope of any variable, method, or class\/package using the PUBLIC keyword.<\/p>\n

\"\"<\/p>\n

Private Access modifier:<\/h2>\n

The private access modifier provides accessibility inside the class we can not access outside the class. We can make any class private using the PRIVATE keyword. If we created a class constructor as private then we can not create an instance of that class as well.<\/p>\n

\"\"<\/p>\n

Protected Access modifier:<\/h2>\n

Protected access modifiers allow the scope to be available within packages as well as sub-class of different packages. We can provide protected accessibility using the PROTECTED keyword.<\/p>\n

\"\"<\/p>\n

Accessibility of access modifiers:<\/h1>\n
