I have to create a hangman game. I am stuck in the last step. In fact, when the user finds the word my input asks yet a letter.
Here an example: (the word to find is "non")
Enter your letter please : n
n _ n
Enter your letter please : o
n o n
Enter your letter please :
n o n
My problem is probably my wordFind, I don't understand how to manipulate this ?
String[] words = {"yess", "non"};
String wordRandom = words[(int) (Math.random() * words.length)];
boolean[] letterGuess = new boolean [wordRandom.length()];
boolean wordFind = false;
int numberAttempt = 5;
while(numberAttempt > 0 && !wordFind){
System.out.println("Number of attempt(s) " + numberAttempt);
for(int i=0; i < wordRandom.length(); i++){
if(letterGuess[i]){
System.out.print(wordRandom.charAt(i));
}
else{
System.out.print("- ");
}
}
System.out.println(" ");
System.out.print("Enter your letter please : ");
char letter = input.next().charAt(0);
int letterFound = 0;
boolean alreadyFound = false;
for(int i=0; i < wordRandom.length(); i++){
if(wordRandom.charAt(i) == letter){
if(letterGuess[i]){
alreadyFound = true;
}
letterGuess[i] = true;
letterFound++;
}
}
if(alreadyFound){
System.out.println("Letter already proposed and it has been found ! ");
} else{
if(letterFound == 1){
System.out.println("The letter is correct ! ");
}
else if(letterFound > 0){
System.out.println("The letter is " + letterFound + " times in the word ! ");
}
else{
numberAttempt--;
System.out.println("The letter is not in the word ! ");
}
}
}
You need to add a solved condition like this
boolean wordFind = false;
int numberAttempt = 5;
boolean solved = false;
while(numberAttempt > 0 && !wordFind && !solved){
after you update letterFound, set solved
letterFound++;
if (letterfound == wordRandom.length()) {
solved = true
}
Then at the end after the while loop, if solved is true, congratulate the user.
You can create a variable int amountCorrect = 0; and use that as a check. Every time the user gets a right letter, add to amountCorrect the number of letters there are. At the beginning of the while loop, create a boolean check that checks if the amountCorrect variable is the same as the length of the wordRandom. I know your code is kind of long, so I put a comment next to the lines where I added code:
String[] words = { "yess", "non" };
String wordRandom = words[(int) (Math.random() * words.length)];
boolean[] letterGuess = new boolean[wordRandom.length()];
boolean wordFind = false;
int numberAttempt = 5;
int amountCorrect = 0; // The amountCorrect variable
while (numberAttempt > 0 && !wordFind) {
System.out.println("Number of attempt(s) " + numberAttempt);
// This is the boolean check
if (amountCorrect == wordRandom.length()) {
System.out.println("You Win!");
break;
}
for (int i = 0; i < wordRandom.length(); i++) {
if (letterGuess[i]) {
System.out.print(wordRandom.charAt(i));
} else {
System.out.print("- ");
}
}
System.out.println(" ");
System.out.print("Enter your letter please : ");
char letter = input.next().charAt(0);
int letterFound = 0;
boolean alreadyFound = false;
for (int i = 0; i < wordRandom.length(); i++) {
if (wordRandom.charAt(i) == letter) {
if (letterGuess[i]) {
alreadyFound = true;
}
letterGuess[i] = true;
letterFound++;
// add to amountCorrect
amountCorrect++;
}
}
if (alreadyFound) {
System.out.println("Letter already proposed and it has been found ! ");
} else {
if (letterFound == 1) {
System.out.println("The letter is correct ! ");
}
else if (letterFound > 0) {
System.out.println("The letter is " + letterFound + " times in the word ! ");
}
else {
numberAttempt--;
System.out.println("The letter is not in the word ! ");
}
}
}
I have to write a program where a user to enter 5 words, these words must be stored into a string array. When the user is finished, you must display the number of times a word beginning with the letter ‘B’ was entered, lower or uppercase, and also re-state the B words. I can't get it to tell me how many 'B' words there is and what they are.I use java, ready to program since I'm a student, I don't use scanner and all that
//Asking user to input 5 words
System.out.println ("Please enter 5 words");
System.out.println ("====================");
//set up loop so that x is the index variable going from 0 to 4
//fill words array with five words
int fromIndex = 0;
int counter = 0;
for (int x = 0 ; x <= 4 ; x = x + 1)
{
System.out.print (" ");
words [x] = keyboardInput.readLine ();
//change word to lowercase
String lower = words[x].toLowerCase();
while(fromIndex !=-1)
{
fromIndex = lower.indexOf("b",fromIndex);
if (fromIndex !=-1)
{
//character was matched
counter = counter + 1;
fromIndex++;
}
}
}
System.out.print ("You entered " + counter + " 'B' words and they were: ");
This is what I get:
Please enter 5 words
Food
Billy
Sill
Bear
Pop
You entered 0 'B' words and they were:
You never reset your fromIndex, and you don't need a fromIndex or a while loop like that. I would use String.startsWith(String). Like,
for (int x = 0; x < 5; x++) {
System.out.print(" ");
words[x] = keyboardInput.readLine();
if (words[x].toLowerCase().startsWith("b")) {
counter++;
}
}
Alternatively,
if (Character.toLowerCase(words[x].charAt(0)) == 'b') {
counter++;
}
You can Use indexOf function on your String. If that is 0 it means your word Starts with b.
for (int x = 0 ; x <= 4 ; x = x + 1)
{
System.out.print (" ");
words [x] = keyboardInput.readLine ();
//change word to lowercase
String lower = words[x].toLowerCase();
if(lower.indexOf("b") == 0){
counter++;
}
}
System.out.print ("You entered " + counter + " 'B' words and they were: ");
Here is the complete version:
public class Bwords {
public static void main(String [] args){
java.util.Scanner input=new java.util.Scanner(System.in);
System.out.println ("Please enter 5 words");
System.out.println ("====================");
String[] words = new String[5];
int count=0;
String [] b_words=new String[5];
for (int x = 0; x <= 4; x++) {
System.out.print(x+1+" word: ");
words[x] = input.next();
if (words[x].toLowerCase().startsWith("b")) {
count++;
b_words[x]=words[x];
}
}
System.out.print ("You entered " + count + " 'B' words and they were: ");
for (String b_word : b_words) {
if (b_word != null)
System.out.print(b_word + " ");
}
}
}
Output
Please enter 5 words
1 word: Food
2 word: Billy
3 word: Sill
4 word: Bear
5 word: Pop
You entered 2 'B' words and they were: Billy Bear

Having trouble exiting while loop when all letters of dashWordB are guessed correctly. Any help greatly appreciated.
Just add the following in your while loop:
if(lettersGuessed == Word.length()){
break;
}
That should help you fix the problem.
Also as suggested by the others change the while condition to the following:
while (lettersGuessed < Word.length())
So your while loop should be the following:
while (lettersGuessed < Word.length()){
for (int i=0; i < Word.length(); i++)
{
if (Word.charAt(i) == letterGuess)
{
dashWordB.setCharAt(i,letterGuess);
lettersGuessed++;
System.out.println("letters guessed: " + lettersGuessed);
System.out.println("word length: " + Word.length());
}
if (i == (Word.length() - 1))
{
i = -1;
System.out.println(dashWordB);
System.out.println("Have another guess: ");
letterGuess = kybd.next().charAt(0);
}
if(lettersGuessed == Word.length()){
break;
}
}
}
Your problem is here: while (lettersGuessed <= Word.length()){
You will exit only if lettersGuessed > Word.length() or if you guessed correctly a letter more than the length of the word.
Try while (lettersGuessed < Word.length()){

You are passing in a char where String is expected. Try using String.valueOf(letter) like this:
if (guessedWord.indexOf(String.valueOf(letter)) >= 0) {
// Your code
}
StringBuilder#indexOf(char) is undefined. You could do
if (guessedWord.indexOf(Character.toString(letter)) >= 0) {
there's no indexOf(char) method for a StringBuilder.
guessedWord.indexOf(letter)
should be
if (guessedWord.toString().indexOf(letter) >= 0) {
