Question
In this assignment, you will write a Java program that plays a simplified version of "Hangman". The computer will pick a random word, and the user will guess letters until they've filled in the entire word. Here is the first part of a sample run of the program (user input is in red): Current word: _ _ _ _ Guess a letter: e The letter is not in the word Guess a letter: i The letter is not in the word Guess a letter: a Current word: _ a _ _ If we keep guessing letters, then here is a potential end of the program run (again, user input is in red): Guess a letter: t Current word: _ a _ t Guess a letter: s The letter is not in the word Guess a letter: n Current word: _ a n t Guess a letter: w Current word: w a n t You guessed it!
Explanation / Answer
HANGMAN PROGRAM EXAMPLE :
public class hangManProject
import java.util.Scanner;
public class hangManProject
{
public static void main( String[] args)
{
Scanner scan = new Scanner( System.in);
int totalMistake = 0;
boolean b = false;
showWelcome();
SecretWord word = new SecretWord();
System.out.println("Your clue: " + word.getClue());
KeyboardInput input = new KeyboardInput();
while (totalMistake < 4 && !word.isSolved())
{
System.out.println(word);
char c = input.getNewLetter();
if (!word.update(c))
totalMistake = totalMistake + 1 ;
}
if (word.isSolved())
System.out.println("Great, you done it.");
else
System.out.println("Sorry, too many errors.");
}
public static void showWelcome()
{
System.out.println( "Welcome to Hangman Game:)!!" );
}
}
public class SecretWord
public class SecretWord
{
String clue, visible, secret;
public SecretWord()
{
String [] wordList = { "Umbrella", "Richard Feynman", "American Gangster", "The Silmarillion" };
String [] clueList = { "Rihanna's song", "Nobel Prize in Physics", "Denzel Washington", "Tolkien" };
int rand;
rand = (int) (Math.random()*4);
secret = wordList[rand];
clue = clueList[rand];
int wordLength = secret.length();
visible = "";
for ( int i = 0; i < secret.length(); i++)
{
char c = secret.charAt(i);
if ( c == ' ' )
visible += c;
else
visible += '_';
}
}
public String getClue()
{
return clue;
}
public String toString()
{
// String s = "";
// for(int i = 0; i < wordLength; i++)
// s = s + "_ ";
// return s;
return visible;
}
// provided by Group 4 and 8
public boolean update(char c)
{
char[] secretArray = new char [secret.length()];
char[] visibleArray = new char [secret.length()];
String s = "";
boolean contains = false ;
//We make the String secret an array
for(int i = 0; i < secret.length(); i++)
{
secretArray[i] = secret.charAt(i);
visibleArray[i] = visible.charAt(i);
}
//We are uptading our empty visible array
for(int k = 0; k < secret.length();k++)
{
if(secretArray[k] == c)
{
visibleArray[k] = c;
contains = true;
}
}
//We are changing our visible array into the visible string
for(int m=0; m < secret.length(); m++ )
{
s = s + visibleArray[m];
}
visible = s;
return contains;
}
//This is a method to check if the secret word is solved
public boolean isSolved()
{
return secret.equalsIgnoreCase(visible);
}
}
public class KeyboardInput
import java.util.ArrayList;
import java.util.Scanner;
public class KeyboardInput
{
// Properties
ArrayList<String> keyList ;
boolean chosen;
//Constructor
public KeyboardInput()
{
keyList = new ArrayList<String>();
}
// Adds and stores the entered key in the Arraylist
public void keyChosen( String key )
{
keyList.add( key );
}
// Checks if the entered key has been chosed before
public boolean hasBeenChosen( String key)
{
chosen = keyList.contains( key );
return chosen;
}
public char getNewLetter()
{
Scanner scan=new Scanner( System.in);
char a;
boolean chosen;
String aTmp; // used to convert a into a String for compatibility with Group 6
do
{
System.out.println("Enter a Letter");
a = scan.next().charAt( 0);
aTmp = "" + a;
chosen = hasBeenChosen( aTmp);
if(!chosen)
keyChosen( aTmp);
else
{
System.out.println("You've already used that one. Please enter a new Letter");
}
}
// we repeat the process until we're out of trials.
while(chosen);
return a;
}
}
