Java help

[namarino]

Hey guys. So my I'm working on a project with a partner. She wrote this code and asked me to take a look at it. When I try to compile it (this is a small portion of a bigger project) it highlights the bold text and says "unexpected type    required: variable; found: value" Can anyone tell me what's going on and how to fix it? I would really appreciate it. Oh and forget all of those brackets at the end there. They are from the earlier parts of the project.

 

public static void letterReplacement (String displayedWord)
    {
        Scanner scan = new Scanner(System.in);
        StringBuilder displayedWord2 = new StringBuilder(displayedWord);
        int lengthOfDisplayedWord = displayedWord2.length();
        int lostGames;
        int guessesLeft = 5;
        int count = 0;

       if (guessesLeft == 0)
       {
            lostGames++;
       }

       else
       {
        for(guessesLeft = 5; guessesLeft <= 0; guessesLeft--)
        {
         for(count=0; count < lengthOfDisplayedWord; count ++)
         {
            System.out.println(displayedWord);
            System.out.println("Guess a letter: ");
            String guessedLetter = scan.next();
           
            if (Character.isWhitespace(displayedWord2.charAt(count)))
            {

               

            }
            else
            {
              if (Character.isLetter(displayedWord2.charAt(count)))
              {

                 

              }
              else
              {
                  if (displayedWord.charAt(count) = (guessedLetter))
                  {

                     

                  }
                  else
                  {

                     

                  }
              }
            }
         }
        }
       }
    }

I reformatted the spacing to make it actually readable, and it doesn't do anything. Whats the code supposed to do? The line it fails on needs to be == not = since its a comparison not an assignment. 

public static void letterReplacement (String displayedWord)    {        Scanner scan = new Scanner(System.in);        StringBuilder displayedWord2 = new StringBuilder(displayedWord);        int lengthOfDisplayedWord = displayedWord2.length();        int lostGames;        int guessesLeft = 5;        int count = 0;       if (guessesLeft == 0)       {            lostGames++;       }       else       {            for(guessesLeft = 5; guessesLeft <= 0; guessesLeft--)            {                  for(count=0; count < lengthOfDisplayedWord; count ++)                   {                        System.out.println(displayedWord);                        System.out.println("Guess a letter: ");                       String guessedLetter = scan.next();                         if (Character.isWhitespace(displayedWord2.charAt(count)))                         {                         //does nothing                          }                          else                          {                                   if (Character.isLetter(displayedWord2.charAt(count)))                                  {                                    //does nothing                                   }                                    else                                   {                                            if (displayedWord.charAt(count) == (guessedLetter))                                            {                                              //does nothing                                             }                                             else                                             {                                                     //does nothing                                             }                                     }            }         }        }       }    }

Sorry about that, I blame it on BlueJ (my teacher wants us using that) And it fails on the very last if statement. Oh and it plays the game hangman. So it has a dictionary to 20 words and displays spaces, then the user has 6 guesses to get the word. The user guesses letters and the program replaces the spaces with the letters if they are correct.

Whats the code supposed to do? The line it fails on needs to be == not = since its a comparison not an assignment. 

Also, the for loop condition should be > 0, not <= 0.

Do you want me to give you the entire code so you can see? It's incomplete but you can at least read it.

[namarino]

Sorry about the spacing. I think it's my editor.

Do you want me to give you the entire code so you can see? It's incomplete but you can at least read it.

I'm just pointing out that the code you listed doesnt actually do anything other than deitterate 'guessesleft' and print a couple lines (the conditionals are all empty). 

 

But if you change the = to an == it should work (or at least compile).

Yes I know, I said that it was part of a bigger project. But it says at that very last if statement  "unexpected type    required: variable; found: value" and it highlights the word "count"

[79wjd]

shouldn't you be using displayedWord2.charAt(count) not displayedWord.charAt(count).

 

You should also change guessedLetter to type char instead of string. 

[namarino]

shouldn't you be using displayedWord2.charAt(count).

Even when I change that it still has the same error. == doesn't work either. Can you put it through your editor and see for yourself?

Did you change guessedLetter to type char 

[namarino]

Did you change guessedLetter to type char 

How exactly do I do that? I was just trying to....

[namarino]

I'm not sure how to scan in a character.

[79wjd]

How exactly do I do that? I was just trying to....

just do: 

char guessedLetter = //scanner; 

 

I'm pretty sure you can use a scanner for a char the same was as a string. 

[namarino]

just do: 

char guessedLetter = //scanner; 

 

I'm pretty sure you can use a scanner for a char the same was as a string. 

char guessedLetter = scan.next(); 

How do you scan in a character though? When I compile this, it highlights the () and says that string cannot be converted to char.

I also get the error

 

Variable 'lostGames' might not have been initialized

Yes, @djdwosk97 already mentioned that one so I didn't want to repeat it. Just wanted to mention the other error in your application.

[namarino]

Could you help me fix that error?

[79wjd]

Could you help me fix that error?

string input = scan.next(); 

char guessedLetter = input.charAt(0);

[namarino]

string input = scan.next(); 

char guessedLetter = input.charAt(0);

error is still there....

[namarino]

Can anyone help me with this? I really don't understand what I'm doing wrong. 

[madknight3]

@djdwosk97 answer should work. (Note String needs to be capitalized)

 

It removed the error for me.

[namarino]

It says that count is a value though.....but it's a variable. It needs a variable and it says that I have a value.
