  • In java access modifiers is the accessibility or scope of a field, method, constructor, or class.
  • The access specifiers are used to define how the variables and functions can be accessed outside the class.
  • We can change the access level of constructors, fields, methods, and class by applying the access modifier.
  • In C++ there are four types of access modifiers, they are:
    • Private
    • Public
    • Protected
    • Default

    • Private

    • The private modifier is only within the class and it cannot be accessed from outside the class.

    Sample Code

    class A{  

    private int data=40;  

    private void msg(){System.out.println("Welcome to Wikitechy");}  

    }  

      

    public class Simple{  

     public static void main(String args[]){  

       A obj=new A();  

       System.out.println(obj.data);//Compile Time Error  

       obj.msg();//Compile Time Error  

       }  

    }  

    Output

    Public

    • The public modifier is everywhere, and it can access from within the class, outside the class, within the package and outside the package.

    Sample Code

    package pack;  

    public class A{  

    public void msg(){System.out.println("Welcome to Wikitechy");}  

    }  

    Output

    Protected

    • The protected modifier is within the package and outside the package through child class.
    • It cannot be accessed from outside the package, if you do not make the child class.

    Sample Code

    package pack;  

    public class A{  

    protected void msg(){
    System.out.println("Welcome to Wikitechy");
    }  

    }  

    Output

    Default

    • The default modifier is only within the package and it cannot be accessed from outside the package.
    • It will be the default, if you do not specify any access level.

    Sample Code

    package pack;  

    class A{  

      void msg(){System.out.println("Welcome to Wikitechy");}  

    } 

    Output
