text: hey people.i am new to java and i am currently constructing a hangman game. the game asks for the user to enter a word(3 or more characters long). then it prompts the user to enter a single character or the complete word in a message input dialog which contains the word lenght replaced by ("_") .. if the user enters a single character then the dashes are replaced by the character the user enters.if the user enters the right word then a message box appears(correct). i am asking for help at the point where the user is prompt to enter a single character or a complete word.how am i going to reappear the inputdialog with the dashes replaced?how is going to check character by character of the hidden word?thx

FAULTY PART !!!!! for (int i=0;i<=word.length(); i++){ cha=word.charAt[i]; if (cha.equals(step2)) { tot2= tot2 + step2; } else{ tot2=tot2 + "_ "; } } } else { if (step2.equals(word)){ JOptionPane.showMessageDialog(null,"You guessed correctly"); } else { JOptionPane.showMessageDialog(null,"You guessed incorrectly"); } } } }
