包含圖像的Applet在瀏覽器中運行時不會顯示它們

Question

好的，我的問題如下：我有一個像圖像庫一樣的小程序。它在eclipse中工作得很好，但是當我將它添加到我的網頁並運行它時，圖像將不會顯示出來，只顯示小程序的其餘部分。

有沒有人有任何想法如何解決？

這是我如何添加它在我的HTML：

<applet code="Sliki.class" width="600" height="330"> 
    <param name="image" value="0.jpg"> 
    <param name="image" value="1.jpg"> 
    <param name.... (rest rest of the photos)..... 
</applet> 

這裏是我的Java代碼：

import javax.swing.*; 
import javax.swing.event.*; 

import java.awt.*; 
import java.util.*; 
import java.io.*; 

import javax.imageio.ImageIO; 

public class Sliki extends JApplet implements ListSelectionListener { 
JFrame frmMain; 
JList lstBooks; 
JScrollPane scrollBooks; 
JLabel lblImage; 
ArrayList<String> books; 
Image image; 

public void init(){ 

    books = new ArrayList<String>(); 
    books.add("Razer Gaming PC - NZXT H440"); 
    books.add("Razer Gaming Laptop"); 
    books.add("Razer Mouse"); 

    books.add("iPhone 5s"); 
    books.add("Samsung Galaxy s4"); 
    books.add("iPhone 6s"); 

    books.add("The Alchemist");

    books.add("The Power");

    books.add("Warcraft 3");

    books.add("Spiderman");

1. 確保將圖像添加到您的罐子文件。
2. 我自己，我通常使用ImageIO.read(URL url)或ImageIO.read(InputStream inputStream)來獲取我在這種情況下的圖像。
3. 難道所有這些if/else塊都被簡化爲一行嗎？ "" + lstBooks.getSelectedIndex() + ".jpg"？
