Weird output

[gandalf5166]

Hey, I'm having trouble with my output. My code has no problems as far as I can see, but here it is:
import java.lang.Math;
import java.util.Scanner;
/**
* @(#)Mastermind.java
*
* Mastermind application
*
* @author
* @version 1.00 2010/2/23
*/
public class Mastermind {

public static void Main(String[]args) {
int number;
int r1;
int r2;
int r3;
int r4;
int g1;
int g2;
int g3;
int g4;
int bulls;
int cows;
int guess;
final int SENTINEL = 0;
int retry = 1;
Scanner input = new Scanner(System.in);
do{

number = (int)(9999 * Math.random() + 0000);
r4 = number % 10;
number /= 10;
r3 = number % 10;
number /= 10;
r2 = number % 10;
number /= 10;
r1 = number % 10;
bulls = 0;
cows = 0; //determine the number and reset the bulls and cows
for (int turn = 1; turn <= 10; turn++) {
System.out.println("Turn " + turn); // tell the user what turn he is on
System.out.println("Please enter your guess (i.e. 1445): ");
guess = input.nextInt();
g4 = number % 10;
number /= 10;
g3 = number % 10;
number /= 10;
g2 = number % 10;
number /= 10;
g1 = number % 10; //evaluate the users guess into single digits
if (g1 == r1)
bulls++;
else if (g1 == r2 || g1 == r3 || g1 == r4)
cows++;
if (g2 == r2)
bulls++;
else if (g2 == r1 || g2 == r3 || g2 == r4)
cows++;
if (g3 == r3)
bulls++;
else if (g3 == r1 || g3 == r2 || g3 == r4)
cows++;
if (g4 == r4)
bulls++;
else if (g4 == r1 || g4 == r2 || g4 == r3)
cows++;
System.out.println("Number of bulls: " + bulls);
System.out.println("Number of cows: " + cows); //check the guess and tell the user how close he was

if (bulls == 4)
{
System.out.println("Code broken by trying " + turn + " times.");
turn = 10; //tell the user that he has won
}
else
{
bulls = 0;
cows = 0; //reset bulls and cows for next guess
}
if (turn == 10 && bulls != 4)
{
System.out.println("Failed to break the code. ");
System.out.println("The answer is: " + r1 + r2 + r3 + r4);
System.out.println("Enter 0 to quit, anything else to continue.");
retry = input.nextInt(); //tell the user he has lost and ask for a retry
}
}
} while (retry != SENTINEL);
}
}


:(
My output is:

-server to select the "server" VM
-hotspot is a synonym for the "client" VM [deprecated]
The default VM is client.

I had capitalized main in the class declaration.

atleast specify the purpose of the application .. that helps in troubleshooting i.e, what your application is upto?
