Mastermind Java Code

[TriSBR]

I need a code for mastermind which allows the user to guess 4 letters from a-f, the player has 10 turns. It will tell the player if they get exact letter and position matches and partial matches for correct letter and wrong position. Here's what I have so far, but doesnt seem right. Need to use private String generateSecretCode(). THANKS!

import java.util.ArrayList;
import java.util.Arrays;


public class Assignment5Code {

	/**Jim Petersen
	 * 11/3/11
	 * The purpose of this program is to create a game called Mastermind using arrays.
	 * @param args
	 */
	private String generateSecretCode() {
	
		char[] correctCode = {'a', 'e', 'b', 'd' };
		
ArrayList<String> varName = Arrays.asList(new String[] { "A", "B", "C", "D", "E", "F" } );
String firstLetter = lettersList.remove((int)(Math.random() * 6));
String secongLetter = lettersList.remove((int)(Math.random() * 5));
String thirdLetter = lettersList.remove((int)(Math.random() * 4));
String fourthLetter = lettersList.remove((int)(Math.random() * 3));
String secretCode = firstLetter + secondLetter + thirdLetter + fourthLetter;
return secretCode; 
	}

private String getGuess() {
}

private int getExactMatches(String secretCode, String guess) {}

public void start() {
	
int numberOfTurns = 0;
System.out.println("You have a maximum of 10 chances to correctly guess a sequence of four non-repeating letters ranging from a to f.");
String secretCode = generateSecretCode();
varName.get(1);
System.out.println("Enter four different letters, seperated by a space");
String guess = getGuess();
String exactMatches = getExactMatches(secretCode, guess);
String partialMatches = getPartialMatches(secretCode, guess); 
System.out.println("Exact (correct letter and position): " + exactMatches);
System.out.println("Partial (correct letter, incorrect position): " + partialMatches);
numberOfTurns--;
if (numberOfTurns == 0) {
System.out.println("You lost. The correct code was: " + secretCode);

if(exactMatches > 3) {
System.out.println("You won!")
numberOfTurns *= 0;
}
}

but doesnt seem right

Does it work the way you want it to? If not, please explain what the problem is.

numberOfTurns *= 0;

What is the above line of code supposed to do?

Figured it out myself. I'm good.

When you get really good, you won't need to post a question for others to look at.
