Complete the ActionPerformed() method. It should do the following:

Take input from enterArea as one character. Ignore any input beyond a singular character.

Verify that the entered character has not already been entered/ submitted. If the character has not been entered, add it to the list of entered characters. Then, check to see if the entered character is a part of the password.

Change the text of wordOutput to reflect the correct letters that have been entered. If the letter was not a part of the word, subtract one life. Update the labels lettersEntered & livesRemaining to reflect these changes.

Check to see if the whole word has been entered. If so, the player has won.

Hint: lettersCorrect is an array of boolean variables which can be used to easily change wordOutput and verify if the word has been guessed.
