爲什麼我的圖像不能顯示在我的佈局中？

Question

我正在使用Java開發這個項目，需要一個圖像來顯示，還有一個生物，以及播放歌曲/聲音的按鈕。我完成了按鈕和生物，但我可以弄清楚如何在佈局的北部顯示圖像以及中間部分的按鈕，任何幫助都會很棒。

這是我的錯誤：在式容器的製造方法的附加（字符串，成分）是不適用的參數（圖像，字符串）

public void init() { 
    // image 
    myPicture = getImage(getCodeBase(), "sample.jpg"); 
    // THIS IS WHERE MY PROBLEM IS vvvvvvv  
    add(myPicture, BorderLayout.NORTH); 

    add(bio); 

    paneSouth.add(play); 
    getContentPane().add(paneSouth, BorderLayout.SOUTH); 
    mySound = getAudioClip(getDocumentBase(), "sample.wav"); 
    play.addActionListener(new ActionListener() { 
     public void actionPerformed(ActionEvent e) { 
      mySound.play(); 
     }});  
} 

public void paint(Graphics g){ 
    g.drawImage(myPicture, 10, 10, this); 
} 

private JPanel paneSouth = new JPanel(); 
private TextArea bio = new TextArea("bio thing"); 
private JButton play = new JButton("Play"); 
private AudioClip mySound; 
private Image myPicture; 

}

編輯：

public void init() { 
    // image 
    ImageIcon icon = new ImageIcon(myPicture); 
    JLabel myLabelImage = new Image(icon); 
    add(myLabelImage, BorderLayout.NORTH); 

    // bio 
    add(bio); 
    add(bio, BorderLayout.CENTER); 

    // sound 
    paneSouth.add(play); 
    getContentPane().add(paneSouth, BorderLayout.SOUTH); 
    mySound = getAudioClip(getDocumentBase(), "sample.wav"); 
    play.addActionListener(new ActionListener() { 
     public void actionPerformed(ActionEvent e) { 
      mySound.play(); 
     }});  
} 

private JPanel paneSouth = new JPanel(); 
private TextArea bio = new TextArea("bio."); 
private JButton play = new JButton("Play"); 
private AudioClip mySound; 
private Image myPicture; 
}

我想你正在使用JApplet，因爲你正在使用Swing組件。嘗試是這樣的：

public class ImageApplet extends JApplet { 

    private JPanel paneSouth = new JPanel(); 
    private JTextArea bio = new JTextArea("bio thing"); 
    private JButton play = new JButton("Play"); 
    private Image myPicture; 
    private ImageIcon icon; 
    private JLabel label; 

    public void init() { 
     try { 
      URL pic = new URL(getDocumentBase(), "sample.jpg"); 
      myPicture = ImageIO.read(pic); 
      icon = new ImageIcon(myPicture); 
      label = new JLabel(icon); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     // add image 
     add(label, BorderLayout.NORTH); 
     // bio 
     add(bio, BorderLayout.CENTER); 
     // sound 
     paneSouth.add(play); 
     add(paneSouth, BorderLayout.SOUTH); 

     // here add your sound declaration and button event... 
    } 

    @Override 
    public void paint(Graphics g) { 
     super.paint(g); 
    } 
} 

並嘗試改變你TextArea的JTextArea，因爲你只使用Swing組件。
