About Default and Protected Access Modifiers
==================================
Default :
# If you dont specify any modifier , by default, it is treated as Default
# Accessible with in the Package
# Accessible with in a class
# It cannot be accessed from outside the package

Protected :
# Accessible with in a package
# Accessible outside a package , but through Inheritance only.
# Can be applied for Data members, Method and Constructor,
# Cannot be applied on the Class

Program for Default:
======================
#1.
package mypack_1;

class ClassA {

void display()
{
System.out.println("This is a method with no access modifier");
}

}
#2.
package mypack_2;

import mypackage_1.ClassA;

public class ClassB
{

public static void main(String args[])
{
ClassA obj= new ClassA();
obj.display(); // Error at compile time
}
}

Program for Protected:
===========================
#1.
package protectedpack_1;

public class classA
{
protected void display()
{
System.out.println("This is a method with protected access modifier");
}
}

#2.
package protectedpack_2;

import protectedpack_1.classA;

class ClassB extends classA
{

public static void main(String args[])
{
ClassB obj=new ClassB();
obj.display();
}
}
