How do you convert the input from a JTextfield from a string to a char?

For Hangman, we have a method checkLetter, which checks to see if the letter the user inputted is in the array char[] that has the word the user is trying to guess for Hangman. Here is the code we have so far: 

 public void playGame(String filename)
  {
//a randomword is read from a textfile, and converted from a string to an array of chars that has a char stored in each index

  randomWord = array[(int)(Math.random() * array.length)];
  int length = randomWord.length();

  char[] arr = randomWord.toCharArray();
 }

Then, we have the method checkLetter.

 public boolean checkLetter()
     {
  char inputLetter = letter.charAt(letter.getText()); //letter is the name of the JTextField where the user inputs the letter they are guessing
     }

We are kind of confused as to what to do next, and we would appreciate any help on how to proceed from here. Thank you!

If the length of the String is (at least) one, you can do this:

String text = letter.getText(); // get the value of the JTextField
char ch = text.charAt(0);       // get the first letter as char

or in one statement, either

char ch = letter.getText().charAt(0);

or 

char ch = letter.getText().toCharArray()[0];
