Can someone help me a java program that write sa showLetters method to be used in a Hangman game. The method should have two parameters: a word and a string of characters representing a sequence of guesses. The method should then return a new string with any guessed letters in their correct position and unguessed letters shown as underscores. For example, the method call: Word.showLetters("computing", "gpo"); would display _o_p____g That is, any letters guessed are shown in their correct location and an underscore represents letters that are not guessed. The method should be a static method of a Word class and could be used as shown in the following program (see section in bold):
Can someone help me a java program that write sa showLetters method to be used in a Hangman game. The method should have two parameters: a word and a string of characters representing a sequence of guesses. The method should then return a new string with any guessed letters in their correct position and unguessed letters shown as underscores.
For example, the method call:
Word.showLetters("computing", "gpo");
would display
_o_p____g
That is, any letters guessed are shown in their correct location and an underscore represents letters that are not guessed.
The method should be a static method of a Word class and could be used as shown in the following program (see section in bold):
import java.util.Scanner; public class TestShowLetters { public static void main(String [] args) { Scanner in = new Scanner(System.in); // Ask the user for a word and some guesses System.out.print("Enter a word and some guesses: "); String word = in.next(); String guesses = in.next(); String show = Word.showLetters(word, guesses); System.out.println(show); } }
And the program would be executed as follows:
$ java TestShowLetters Enter a word and some guesses: computing gpo _o_p____g
Note : Your method will actually be tested with the program below:
import java.util.Scanner; public class Main { // generate the alphabet static String getAlphabet() { String alphabet = ""; for(int i = 0; i < 26; i++) alphabet += (char) ('a' + i); return alphabet; } static boolean contains(String word, char let) { for(int i = 0; i < word.length(); i++) if(word.charAt(i) == let) return true; return false; } public static void main(String []args) { Scanner input = new Scanner(System.in); String alphabet = getAlphabet(); System.out.println("Enter a word:"); String word = input.next(); String guesses = ""; // Start with no guesses // 1. try every second letter in the alphabet for(int i = 0; i < alphabet.length(); i += 2) if(contains(word, alphabet.charAt(i))) { guesses += alphabet.charAt(i); // Try this letter System.out.println(Word.showLetters(word, guesses)); } // 2. Try the same thing backwards guesses = ""; // reset guesses for(int i = alphabet.length() - 1; i >= 0; i -= 2) if(contains(word, alphabet.charAt(i))) { guesses += alphabet.charAt(i); // Try this letter System.out.println(Word.showLetters(word, guesses)); } // 3. try no guesses (i.e. empty string) System.out.println(Word.showLetters(word, "")); // 4. all letters for(int i = 0; i < alphabet.length(); i++) if(contains(word, alphabet.charAt(i))) guesses += alphabet.charAt(i); // Try this letter System.out.println(Word.showLetters(word, guesses)); } }
This code reads in a word and then tests your method in four different ways
- Every second letter in alphabetic order.
- Every second letter in reverse alphabetic order.
- No letters
- Every letter in the word, though in alphabetic order.
