Setting array to JTextField then removing

Question

I am wanting to get a JTextField filled with an array A-Z. Then when a user pressed e.g. P on the keyboard, that letter will be removed from the JTextField.

So far all I have is the following, I know it's nowhere close so apologies (And I know it wont work).

tf_1 = new JTextField();
String[] alphabet = {"A", "B" //etc};
tf_1.setText(alphabet);
tf_1.addKeyListener(new KeyAdapter() {
 public void keyTyped(KeyEvent e) {
  // Remove letter if typed.
 }
}

Inside the key listener, how can I add code to remove the typed letter from the alphabet array?

Not so fine, but works

//Frame maninFr = new Frame();
JTextField tf_1 = new JTextField();
//maninFr.add(tf_1);
//maninFr.show();

String[] alphabet = {"A","B"};
tf_1.setText(Arrays.toString(alphabet));
tf_1.addKeyListener(new KeyListener() {

 @Override
 public void keyTyped(KeyEvent e) {}

 @Override
 public void keyReleased(KeyEvent e) {
  String input = tf_1.getText();
  char pressed = e.getKeyChar();
  String newInput = input.replaceAll(Character.toString(pressed), "");
  System.out.println("pressed: " + pressed);
  System.out.println("newin : " + newInput);
  tf_1.setText(newInput);
 }

 @Override
 public void keyPressed(KeyEvent e) {}
});
