Access Modifiers-3

Access Modifiers-3

3) protected

The protected access modifier is accessible within package and outside the package but
through inheritance only.

The protected access modifier can be applied on the data member, method and constructor.
It can't be applied on the class.

Example of protected access modifier

In this example, we have created the two packages pack and mypack. The A class of pack
package is public, so can be accessed from outside the package. But msg method of this
package is declared as protected, so it can be accessed from outside the class only
through inheritance.

    //save by A.java 
     
    package pack; 
    public class A{ 
    protected void msg(){System.out.println("Hello");} 
    } 

    //save by B.java 
     
    package mypack; 
    import pack.*; 
     
    class B extends A{ 
      public static void main(String args[]){ 
       B obj = new B(); 
       obj.msg(); 
      } 
    } 

Output:Hello
