java - 将 jFileChooser 中选择的文件设置为字符串？

Question

我想将 jFileChooser 中选择的文件设置为 stringbuilder 段的字符串，但是采用特定的模式。即

        {
            sb.append(" -file").append(mods);
        }

“mods”是文件，每个文件之间是一个“-file”，例如，如果我选择 file1.wad、file2.wad 和 file3.pk3，则程序所需的输出将是

-file file1.wad -file file2.wad -file file3.pk3

我该怎么做？

编辑这是我的更多代码。 Paco Abato 建议的代码到底会去哪里？因为在代码的底部它会吐出大量错误。

private void RunGameButtonActionPerformed(java.awt.event.ActionEvent evt) {                                              
    String PlayerCount = PlayerCountHere.getText();
    String HostIP = HostIPHere.getText();
    //String MapWarp = MapWarpBox.getName();
    try
    {
        //Basic game launching command.
        StringBuilder sb = new StringBuilder("cmd.exe /C start C:\\mygame\\game.exe");

        if(HostButton.isSelected())
        {
            //Add the Host Flag and add the Player Count from the box
            sb.append(" -host ").append(PlayerCount);
        }
        if(JoinButton.isSelected())
        {
            //Add the Join Flag and add the Host IP from the box
            sb.append(" -join ").append(HostIP);
        }
        //Launch the game
        Process process = Runtime.getRuntime().exec(sb.toString());
    }
    catch(IOException e)
    {
        //Log Error
    }
}

很简单:

for (File file : selectedFiles) {
    sb.append(" -file ").append(file.getName());
}
