The access modifiers in Java specifies the accessibility or scope of a field, method, constructor, or class. We can change the access level of fields, constructors, methods, and class by applying the access modifier on it.

There are two types of modifiers in Java access modifiers and non-access modifiers.

      Access modifiers:

1. Private: The access level of a private modifier is only within the class. It cannot be accessed from outside the class.
2. Default: The access level of a default modifier is only within the package. It cannot be accessed from outside the package. If you do not specify any access level, it will be the default.
3. Protected: The access level of a protected modifier is within the package and outside the package through child class. If you do not make the child class, it cannot be accessed from outside the package.
4. Public: The access level of a public modifier is everywhere. It can be accessed from within the class, outside the class, within the package and outside the package.
   
   

   Non-Access Modifiers

   Java provides a number of non-access modifiers to achieve many other functionality.
   1. The static modifier for creating class methods and variables.
   2. The final modifier for finalizing the implementations of classes, methods, and variables.
   3. The abstract modifier for creating abstract classes and methods.
   4. The synchronized and volatile modifiers, which are used for threads.
