the josephus file is the following :
//**Here is the file
====================================================================
class Josephus
{
Node first;
Node last;
Node ring;

Josephus()
{
first = null;
last = null;
ring = null;
}

Node circle(int key)
{
Node first = new Node(key);
Node last = first;
first.key = key;

for (int j = key - 1; j > 0 ; j--)
{
Node ring = new Node(j);
ring.key = j;
ring.next = first;
first = ring;
}
last.next = first;
return last;
}

public void suicide()
{
Node reference = circle(A);
while (reference != reference.next) //when there are still
more than 1 person
for (int i = 1; i < B; i++)//you can still execute the B
person
reference = reference.next;
System.out.println( "-R.I.P # "+ reference.next.key );
reference.next = reference.next.next;
System.out.println();
System.out.println("Josephus has to take position ( " +
reference.key + " ) to survive!");

}
}

====================================================================
//**Here is the App file
====================================================================
import java.io.*;
//---------------
class JosephusApp
{
public static void main (String[] args) throws IOException
{
InputStreamReader inStream = new InputStreamReader(System.in);
BufferedReader stdin = new BufferedReader(inStream);
Josephus Josephus = new Josephus();
String inData;
int A;
int B;

System.out.println("Welcome to 'Josephus, a smart jew' problem
solver.");

System.out.println("**************************************************");
System.out.println("How Many Jews want to commit suicide
today?");
inData = stdin.readLine();
A = Integer.parseInt(inData);

if (A <=0)
{
System.out.println("Try a positive number!");
}
else
{
System.out.println();
System.out.println("Eliminate one every :");
inData = stdin.readLine();
B = Integer.parseInt(inData);
System.out.println();

if (B <=0)
{
System.out.println("Try a positive number!");
}

else
{
Josephus.suicide();
}
}
}
}

====================================================================
//**Here is the error
