I need some help with this. For my class I have to make a game called hexo, basically
"Hexo is a game loosely based on the television game show Lingo. Rather than trying to guess 5 letter words (as in Lingo) the Hexo player will have sixteen tries to guess randomly generated 5 digit hexadecimal numbers.
The hexadecimal ‘secret numbers’ will not have any duplicated digits.
Each time the user enters a guess:
• The number of the guess will be displayed.
• The number of matching digits will be displayed.
• The number of matches in the correct position will be displayed.
If the user guesses the number; the ‘secret number’ will be displayed, a winning message will be displayed, the number of guesses will be displayed and the game will end.
If the user does not guess the number by the sixteenth try, a losing message will be displayed, the ‘secret number’ will be displayed, and the game will end.
For each guess, the user’s entry will be checked for valid hexadecimal digits and for having a length of 5 characters.
Error handling will be simple:
• If non-hexadecimal characters are detected, the user will get a message, but the guess will be processed normally and will count as a try.
• If the guess is longer than 5 characters, the user will get a message, the guess will be truncated, processed normally and will count as a try
• If the guess is shorter than 5 characters, the user will get a message, the guess will have an appropriate number of blank spaces added, be processed normally and will count as a try
"
I've Figured out most of it. I have a class that generates the random hex fine (using a method called create();) but Im coding in my other class that handles all the UI stuff and i cant figure out how to
-Have the scanner count how many times the user has inputted a guess
-How to only have the program run 16 times
- How to display the guess #, number of correct digits, and how many are in the correct position
Heres My Code:
import java.util.Scanner;
/**

public class HexoGame
{
/**

public void runHexo()
{
final int WORDLENGTH = 5;
HexGen obj = new HexGen();
Scanner scan = new Scanner(System.in);
String secretHex = obj.create();
int turn = 0;
final int MAX = 16;
String guess = new String();
// int a = secretHex.charAt(0);
// int b = secretHex.charAt(1);
// int c = secretHex.charAt(2);
// int d = secretHex.charAt(3);
// int e = secretHex.charAt(4);
// try
// {
// // int aa = guess.charAt(0);
// // int bb = guess.charAt(1);
// // int cc = guess.charAt(2);
// // int dd = guess.charAt(3);
// // int ee = guess.charAt(4);
//
// }
//
// catch(Exception f)
