为以下代码添加注释: private JTextArea textArea = new JTextArea(); private JScrollPane scrollPane = new JScrollPane(textArea); private JFileChooser fileChooser = new JFileChooser(); private String currentFile = "Java文本编辑器"; private boolean saved = true; private JToolBar toolBar = new JToolBar(); private JButton saveButton = new JButton("保存"); private JButton cutButton = new JButton("剪切"); private JButton copyButton = new JButton("复制"); private JButton pasteButton = new JButton("粘贴"); private JButton findButton = new JButton("查找"); private JPanel statusBar = new JPanel(); private JLabel statusLabel = new JLabel("准备中");

好的,以下是为代码添加的注释:
```java
private JTextArea textArea = new JTextArea(); // 创建文本区域
private JScrollPane scrollPane = new JScrollPane(textArea); // 创建滚动面板,并将文本区域添加到其中
private JFileChooser fileChooser = new JFileChooser(); // 创建文件选择器,用于打开和保存文件
private String currentFile = "Java文本编辑器"; // 当前打开或保存的文件名
private boolean saved = true; // 表示当前文本是否已保存
private JToolBar toolBar = new JToolBar(); // 创建工具栏
private JButton saveButton = new JButton("保存"); // 创建保存按钮
private JButton cutButton = new JButton("剪切"); // 创建剪切按钮
private JButton copyButton = new JButton("复制"); // 创建复制按钮
private JButton pasteButton = new JButton("粘贴"); // 创建粘贴按钮
private JButton findButton = new JButton("查找"); // 创建查找按钮
private JPanel statusBar = new JPanel(); // 创建状态栏
private JLabel statusLabel = new JLabel("准备中"); // 创建状态栏标签
```
希望以上注释可以帮助您更好地理解代码的含义。
