Generate unique letters

[bl00dr3d]

Hey man thanks for that it was real helpful. But for some reason my loop just isnt operating. Like using the following code I am only able to generate one letter..
Heres the code -

private String generateSecretCode() {
        String secretCode = "";
	int count = 0;
	String letters = "ABCDEF";
	while(count < 4) {
	    String code = "";
	    char randomLetter = letters.charAt((int)(Math.random() * 6));
            if(code.indexOf(randomLetter) == -1) {
	        String newCode = code + randomLetter;
	        count++;
	        secretCode = newCode;
	    }
	}

	return secretCode;
}

javabeginer... it would be better if you started your own post about this topic.
