Java选择：以JAR或Base64顺序存储图像？

现在,我有这些卡的图像,我也有Base64格式的图像.我试图通过3种不同的方式显示它们.我为每个人编写了一个小程序用于演示目的.

以下是我尝试过的3种方法：

1).将图像存储在JAR文件中：

非常直截了当.图像进入JAR,Java代码从那里读取它们.之后,它创建一个包含所有这些的JComboBox并显示它：

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JComboBox;
import javax.swing.ImageIcon;

public class ImagesFromJAR
{
    private JFrame mainframe;

    public ImagesFromJAR ()
    {
        ImageIcon[] cardslist = new ImageIcon[52];

        for (int i = 0; i < 52; ++i)
        {
            cardslist[i] = new ImageIcon (getClass (). getResource ((this.getImagePath (i))));
        }

        JComboBox cardsbox = new JComboBox (cardslist);
        cardsbox.setSelectedIndex (0);
        cardsbox.setEditable (false);

        this.mainframe = new JFrame ();
        this.mainframe.setDefaultCloSEOperation (JFrame.DISPOSE_ON_CLOSE);
        this.mainframe.setSize (150,150);
        this.mainframe.setLayout (null);

        cardsbox.setBounds (20,20,55,45);
        this.mainframe.add (cardsbox);

        this.mainframe.setVisible (true);
    }

    private String getImagePath (int index)
    {
        switch (index)
        {
            case 0: return "images/2c.gif";
            case 1: return "images/3c.gif";
            case 2: return "images/4c.gif";
            case 3: return "images/5c.gif";
            case 4: return "images/6c.gif";
            case 5: return "images/7c.gif";
            case 6: return "images/8c.gif";
            case 7: return "images/9c.gif";
            case 8: return "images/Tc.gif";
            case 9: return "images/Jc.gif";
            case 10: return "images/Qc.gif";
            case 11: return "images/Kc.gif";
            case 12: return "images/Ac.gif";
            case 13: return "images/2d.gif";
            case 14: return "images/3d.gif";
            case 15: return "images/4d.gif";
            ......................................
            default: return null;
        }
    }

    public static void main (String[] args)
    {
        javax.swing.SwingUtilities.invokeLater (new Runnable ()
        {
            public void run ()
            {
                ImagesFromJAR t = new ImagesFromJAR ();
            }
        });
    }
}

2).将图像以Base64格式存储在文本文件中：

我以Base64格式转换每个图像,然后存储在文本文件中. Java代码读取该文件并通过解码文件中的行来重新创建图像.之后,创建并显示JComboBox：

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JComboBox;
import javax.swing.ImageIcon;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.FileInputStream;
import java.io.IOException;

public class CodeFromFile
{
    private JFrame mainframe;

    public CodeFromFile ()
    {
        ImageIcon[] cardslist = new ImageIcon[52];

        InputStreamReader in = null;
        BufferedReader buff;

        int index = -1;

        try
        {
            in = new InputStreamReader (new FileInputStream ("card.encodings.txt"));
            buff = new BufferedReader (in);

            String line;
            byte[] ba;

            while ((line = buff.readLine ()) != null)
            {
                if (line.length () < 10)
                {
                    continue;
                }

                index++;

                ba = Base64.decode (line);

                cardslist[index] = new ImageIcon (ba);
            }
        }
        catch (IOException e)
        {
            e.printStackTrace ();
        }
        finally
        {
            if (in != null)
            {
                try
                {
                    in.close ();
                }
                catch (IOException e2) {}
            }
        }

        JComboBox cardsbox = new JComboBox (cardslist);
        cardsbox.setSelectedIndex (0);
        cardsbox.setEditable (false);

        this.mainframe = new JFrame ();
        this.mainframe.setDefaultCloSEOperation (JFrame.DISPOSE_ON_CLOSE);
        this.mainframe.setSize (150,45);
        this.mainframe.add (cardsbox);

        this.mainframe.setVisible (true);
    }

    public static void main (String[] args)
    {
        javax.swing.SwingUtilities.invokeLater (new Runnable ()
        {
            public void run ()
            {
                CodeFromFile t = new CodeFromFile ();
            }
        });
    }
}

card.encodings.txt的内容是这样的：

..它继续为每个图像/卡.

3).第三种方法是将图像直接存储在源代码中作为Base64字符串.像这样：

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JComboBox;
import javax.swing.ImageIcon;

public class CodeFromSource
{
    private JFrame mainframe;

    public CodeFromSource ()
    {
        ImageIcon[] cardslist = new ImageIcon[52];

        byte[] ba;

        for (int i = 0; i < 52; ++i)
        {
            ba = Base64.decode (this.getImageCode (i));
            cardslist[i] = new ImageIcon (ba);
        }

        JComboBox cardsbox = new JComboBox (cardslist);
        cardsbox.setSelectedIndex (0);
        cardsbox.setEditable (false);

        this.mainframe = new JFrame ();
        this.mainframe.setDefaultCloSEOperation (JFrame.DISPOSE_ON_CLOSE);
        this.mainframe.setSize (150,45);
        this.mainframe.add (cardsbox);

        this.mainframe.setVisible (true);
    }

    private String getImageCode (int index)
    {
        switch (index)
        {
            case 0: return "R0lGODlhHgAmAMQAAAAAAP///+7u7t3d3czMzLu7u6qqqpmZmYiIiHd3d2ZmZlVVVURERDMzMyIiIhEREf///wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAEAABAALAAAAAAeACYAAAXKIAQBZGme6CmOQeu+cAwDrGzfLonvss7/LR/u8AA0CDuh7WB6CHBKGeOEgAJ2RdPCunNQuTIFwLE4lR+H3jWWSKEMsWgr6y4p4msYvTQ93Wd5LwgnCQd9JQV4NoNjBwIMAYwNcIo8ZVVJgTIJhwuYNnIubW6UlUA8oaemqjeprDmaMQN9DEhgN5MBBA5OtzIHtgEGAJ9qpwLEvjsDAImtsTcIkMo3Ag4DmUAMztSbaajQMAmfCdig4aInDt3pfuyvQTXwMyt19ikiIQA7";
            case 1: return "R0lGODlhHgAmAMQAAAAAAP///+7u7t3d3czMzLu7u6qqqpmZmYiIiHd3d2ZmZlVVVURERDMzMyIiIhEREf///wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAEAABAALAAAAAAeACYAAAXMIAQBZGme6CmOQeu+cAwDrGzfLonvss7/LR/u8AA0CDuh7WB6CHBKGeOEgAJ2RdPCunNQuTIFwLE4lR+H3jWWSKEMsWgr6y4p4msYvTQ93Wd5LwgnCQd9JQV4NoNjBwIMAYwNcIo8ZVVJgTIJhwuYNnIubW6UlUA8oaemqjeprDmaMowMA5k7B2kEDg22OJ+DT62xNwtbYDsDC5C9OAYkD6Wgw7JFSMKnzp9qqg/aq8gAidc3BQB3j3/jNgINJA3e26+tNfIzK3X4KSIhADs=";

                CodeFromSource t = new CodeFromSource ();
            }
        });
    }
}

(我不得不删除一些交换机案例,因为StackOverflow上有30 K字符限制)

这些方法中的每一个都产生相同的结果,即：

PS：Base64类只是一些编码/解码Base64信息的实用程序类(您可以在下面的链接中找到它).

如果你想要所有的资源(图片,源代码等),你可以从这里获得它们：Resources

现在我们清除了……我想要的是知道这三种方法中的哪一种更好.每个人的优点和缺点是什么？我应该使用哪一个？为什么？我也在谈论JAR文件损坏的可能性.

我唯一不关心的是表现.
