## Undo / Redo 구현 - UndoableEditListener
```java
// 언두 매니저를 생성하고, 텍스트 문서에 리스너를 통해 연결한다. 
final UndoManager undoManager = new UndoManager();
textArea.getDocument().addUndoableEditListener(undoableEditEvent -> 
        undoManager.addEdit(undoableEditEvent.getEdit()));

// 버튼을 통해서 액션을 처리한다.
toolBar.add(new AbstractAction("Undo") {
    @Override
    public void actionPerformed(ActionEvent actionEvent) {
        if (undoManager.canUndo()) {
            undoManager.undo();
        }
    }
});
toolBar.add(new AbstractAction("Redo") {
    @Override
    public void actionPerformed(ActionEvent actionEvent) {

        }
    }
});
```

## DocumentListener

    }

    @Override
    public void removeUpdate(DocumentEvent documentEvent) {

    }

    @Override
    public void changedUpdate(DocumentEvent documentEvent) {

    }
});
```

```java
textArea.addCaretListener(new CaretListener() {
    @Override

        int mark = caretEvent.getMark();
    }
});
