Answer 1

DataTF.addKeyListener(new KeyAdapter() {
            @Override
            public void keyTyped(KeyEvent eve) {
                String AllowedData="0123456789.";
                char enter = eve.getKeyChar();
                if (!AllowedData.contains(String.valueOf(enter))) {
                    eve.consume();
                }
            }       
        });
