Question

JAVA

Develop a letter guessing game in this assignment using Java. Requirements: 1). When the game is started, generate a random letter between A and Z; 2). Display a message "I have a secret letter (A to Z), can you guess what it is?"; 3). Read the user's answer; 4). Compare the user's answer and the random secret letter generated; 5). If the user answer is before the random secret letter in the alphabet, display "Incorrect. Try something bigger" and go to Step 2; 6). If the user answer is after the random secret letter in the alphabet, display "Incorrect. Try something smaller" and go to Step 2; 7). If the user answer is the same as the random secret letter, display "Well done. Want to play again (y/n)?"; 8). Read the user's answer. If the answer is 'y', go to Step 1. If the answer is 'n', go to Step 9; 9). Display "Thanks for playing the game. Goodbye!". The program stops.

Answer 1

Code:

import java.util.*;
public class LetterGuessing {

    public static void main(String[] args) {
            Scanner scan = new Scanner(System.in);
        String choice;
            do{          
        choice="y";
            System.out.println("I have a Secret Letter (A-Z) Can you guess it?");
            String user_letter=scan.nextLine();
            char input_letter=Character.toUpperCase(user_letter.charAt(0));
            char[] chars ={'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'};
            int[] range={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26};
            int user_int=0;
            int user_loop=0;
            char rand_letter=chars[(int)(Math.random()*26)];
            int comp_int=0;

                for(int i=0;i<chars.length;++i)
                {
                    if(rand_letter==chars[i])
                    {

                        comp_int=range[i];
                    }
                }
                //this loop is for getting the int value of user inputted letter
                for(char i:chars)
                {
                    if(input_letter==i)
                    {
                        user_int=range[user_loop];
                    }
                    ++user_loop;
                }

                 //test the entered letter of user
            if(input_letter==rand_letter)
            {
                System.out.println("Correct Guess");
                System.out.println("The letter is:"+rand_letter);
       System.out.println("Do you want to play again?(y/n)");
       choice=scan.next();
            }
            //test the entered letter of user if greater than computer input
            else if(user_int>comp_int)
            {
                System.out.println("Incorrect Guess");
                System.out.println("Try Something Smaller");
                System.out.println("The letter is:"+rand_letter);
            continue;
            }
            //test the entered letter of user if lesser than computer input
            else if(user_int<comp_int)
            {
                System.out.println("Incorrect Guess");
                System.out.println("Try Something higher");
                System.out.println("The letter is:"+rand_letter);
            continue;
            }
   }
        while(choice.equalsIgnoreCase("y"));

    }
  
}

Output:
