java - Public vs. Protected abstract class method

Is there any security/access difference when making a package access
level abstract class's non-static methods public vs making them protected? Only classes
from within the same package that extend the abstract class can access the non-static
methods anyway right? So, does it matter whether those non-static methods are public or
protected since the abstract class itself places restrictions on who can extend
it?

abstract class MyClass
            {

 protected void myFunction(){
 System.out.println("Only
            child classes can print this");
 }
}

abstract
            class MyClass {
 public void myFunction(){

            System.out.println("Still, only child classes can print this");

            }
}

Answer

The public abstract
method will be accessible in the other package where as the
protected abstract method can not be accessed. Check the
example below.

An abstract class with both
public and protected abstract
methods

package
            package1;

public abstract class MyClass {
 abstract
            protected String method1();

 abstract public String
            method2();
}

Another
package which extends the class and implements the abstract
class.

package
            package2;

import
            package1.MyClass;


public class MyClassImpl extends
            MyClass {
 @Override
 protected String method1() {
 return
            "protected method";
 }

 @Override
 public
            String method2() {
 return "public method";

            }

}

Main
class for accessing the abstract method.

package
            package2;

import package1.MyClass;

public
            class MainClass {

 static MyClass myClass = new
            MyClassImpl();

 public static void main(String[] args) {

            System.out.println(myClass.method1()); // This is compilation error.

            System.out.println(myClass.method2());

            }
}
