Question about the task

Resolved

Implement the initEditor() method, which initializes the editor panes. It must:
6.1. Set "text/html" as the content type for the htmlTextPane component.
Find and use the appropriate method.
6.2. Create a new local JScrollPane component based on htmlTextPane.
6.3. Add a tab named "HTML" and the component from the previous step to tabbedPane.
6.4. Create a new local JScrollPane component based on plainTextPane.
6.5. Add another tab named "Text" and the component from the previous step to tabbedPane.
6.6. Set the preferred pane size on tabbedPane.
6.7. Create a TabbedPaneChangeListener object and set it as a change listener on tabbedPane.
6.8. Add our tabbed pane to the center of the content pane of the current frame.
You can get the current frame's content pane using the getContentPane() method, which is inherited from JFrame.
Think about which method you need to call and with which arguments for the tabbed pane to be displayed in the center of the current frame's content pane.
After starting the application, you can see the latest results: two independent tabs (HTML and Text), and each of them lets you enter your own text.

Requirements:

1. In the initEditor() method, the htmlTextPane component's content type must be set to "text/html" through the setContentType setter.
The initEditor() method should create a new local JScrollPane component using a constructor that takes htmlTextPane.
In the initEditor() method, a tab named "HTML" and a JScrollPane component created based on htmlTextPane must be added to the tabbedPane component.
The initEditor() method should create a new local JScrollPane component using a constructor that takes plainTextPane.
In the initEditor() method, a tab named "Text" and a JScrollPane component created based on plainTextPane must be added to the tabbedPane component.
In the initEditor() method, the preferred pane size must be set for the tabbedPane component using the setPreferredSize setter.
The initEditor() method must add a TabbedPaneChangeListener to the tabbedPane component using the addChangeListener method.
The initEditor() method must add the tabbed pane to the center of the current frame's content pane using the getContentPane().add() method.

public void initEditor() {
    htmlTextPane.setContentType("text/html");

    JScrollPane htmlScorllPane = new JScrollPane(htmlTextPane);
    tabbedPane.addTab("HTML", htmlScorllPane);

    JScrollPane plainTextScrollPane1 = new JScrollPane(plainTextPane);
    tabbedPane.addTab("Text", plainTextScrollPane1);

    tabbedPane.setPreferredSize(new Dimension(700, 500));

    tabbedPane.addChangeListener(new TabbedPaneChangeListener(this));

    this.getContentPane().add(tabbedPane, BorderLayout.CENTER);
}
