    Default need help with hangman game project(begginer)

    I have been assignedfrom my university teacher to write a java source code for a hangman game.I have been stuck on the guess method where the player guess a character(especially when he's right).Here is what I have done so far!
    <public class Hangman
    {
     
        private static int ALLOWDED_MISTAKES=7;
        private String secretWord;
        private int noOfMistakes;
        private int chances=7-noOfMistakes;
     
        public  Hangman()
        {
            newGame();
        }//Hangman constructor
     
        public void newGame()
        {
            noOfMistakes=0;
            secretWord=Words.randomWord();
                    System.out.println();
            System.out.println("* * * * * * * * * * * * * * * * * * * * * * * * * * * * *");
            System.out.println("* * * * * * * * * *  N E W   G A M E  * * * * * * * * * *");
            System.out.println("* * * * * * * * * * * * * * * * * * * * * * * * * * * * *");
            System.out.println();
            System.out.print("The word is:");
            for (int i=1;i<=secretWord.length();i++)
              System.out.print("_");
            System.out.println();
            System.out.println();
            System.out.println("You have 7 chances to find the word");
            System.out.println("use method \"guess(char c)\" to guess a character");
            System.out.println("from: 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");
            System.out.println("or use method \"giveUp()\" to stop playing");
     
        }//newGame
     
        public void giveUp()
        {
            System.out.println();
            System.out.println("* * * * * * * * * * * * * * * * * * * * * * * * * * * * *");

            System.out.println("* * * * * * * * * * * * * * * * * * * * * * * * * * * * *");
            System.out.println();
            System.out.println("The hidden word is "+secretWord);
            System.out.println();
            System.out.println("Use method \"newGame()\"to start a new game.");
        }//giveUp
     
     
         public void guess(char c)
     
     
     
     
                    if (!Character.isLetter(c)){

                    if (secretWord.indexOf(c) == -1){
                            noOfMistakes++;
                            System.out.println("wrong guess,try again");
                            System.out.println("your remaining chances are "+chances);
                                                    if (noOfMistakes==ALLOWDED_MISTAKES){

    I have been stuck on the guess method
    Can you explain what the problem is you are stuck on? What are you having problems with?

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    If the word was: BLANKET and the user guessed: N
    then what would the code do?
