The method KeyPressed(KeyEvent) from the type new KeyAdapter(){} is never used locally

[Nicol Green]

I have following code and for KeyPressed it shows me error: "The method KeyPressed(KeyEvent) from the type new KeyAdapter(){} is never used locally". I want to validate input in JFormattedTextField.

JFormttedTextField textField = new JFormattedTextField();

textField.addKeyListener(new KeyAdapter (){
			public void KeyPressed(KeyEvent e) {
				char c = e.getKeyChar();
								
				if (!((Character.isDigit(c) ||
					      ((c == KeyEvent.VK_BACK_SPACE)) ||
					      ((c == KeyEvent.VK_DELETE))))) {
					        getToolkit().beep();
					       e.consume();
					    }
					  }					  			
			});
	}

Why it cannot be read ?

Please check the spelling carefully; you don't usually start method names with capital letters. Put the @Override annotation before the heading of that method and see whether you are getting any compiler errors.
The problem with Adapter classes is that it is possible to miss such tiny errors, which mean the method you think is being called is never called. The @Override annotation should always be used to catch that problem.

hmm, what a shame..

Sorry, I really didn't noticed, it happens when you looking the same code over and over again..
Thanks!

Lots and lots of people do that. That is nothing to worry about. Remember the @Override annotation.
