Java Protected Variables can be accessed inside same package without inheritance how?

Java Protected Variables can be accessed inside same package without
inheritance how?

Please see below program and comments:
Please tell me how another class can access protected member without
inheritance? I have compiled and run this program at my end.
class Sample3
{
final protected String Var1 = "Sample 3 Final Varaible";
final private String Var2 = "Sample 3 Final Varaible";
}//class Sample3
class Sample4
{
public static void main(String args[])
{
Sample3 s3=new Sample3();
//System.out.println(s3.Var2);// Line 12 : this is not accessible as
the Private member is being accessed
System.out.println(s3.Var1);//Line 13 : this access the protected
member but i have not used inheritance between 2 classes Sample3 and
Sample4
}//end of main
}/class Sample4
Var1 is the Class protected member. Var2 is the class private member. I am
creating the Object of the Sample3 inside Sample4. Line 12 is clearly an
error but how it can compile line 13?
