Which access specifier can be used for a class so that its members can be accessed by a different class in the same package?

    import java.util.*;

    class output 

    {

        public static void main(String args[]) 

        {

            Stack obj = new Stack();

            obj.push("A");

            obj.push("B");

            obj.push("C");

            obj.push("E");

            obj.pop();

            obj.push("D");

System.out.println(obj.peek());

        }

    }

Predict the output of the following Java code:

public class Abekus {

public static void main(String[] args) throws InterruptedException

{

Abekus A = new Abekus();

A = null;

System.gc();

Thread.sleep(500);

System.out.println("Main()");

}

protected void finalize() {

int i=0, j=77;

System.out.println("Finalize()");

System.out.println(j/i);

}

}
