如何在不同 PC 上的 java 项目中使用下载的字体？

Question

我下载了“Retro Gaming”字体 (https://www.dafont.com/retro-gaming.font)，以便在我的 Java 项目中使用它。这个项目需要在每台机器上运行我运行它。我的问题是：如何或在哪里放置字体以便所有计算机（即使没有安装它）都可以使用它？我认为 gradle 可能是一个不错的解决方案，但我在互联网上找不到任何相关信息。

示例代码为：

public PlayerOneLabel() {
        this.setText("PLAYER 1");
        this.setForeground(Color.white);
        this.setFont(new Font("Retro Gaming", Font.BOLD, CenterOnDefaultScreen.center().height*2/100));
        }

这显然运行仅在已安装该字体的 PC 上。

将字体文件保存在任何你喜欢的地方...将它与你的游戏文件的其余部分放在一起或放在资源文件夹中。如果它只是为了您的游戏，则不需要去特别的地方。您可以使用以下方法在需要时加载字体：

/**
 * Loads a Font file and returns it as a Font Object. This method does try to 
 * utilize the proper Font Type Resource (TrueType or Type1) but will default 
 * to TrueType if the resource type can not be established.
 * 
 * @param fontFilePath (String) Full path and file name of the font to load.<br>
 * 
 * @param fontStyle (Integer) The Font Style to use for the loaded font, for 
 * example:<pre>
 * 
 *      Font.PLAIN
 *      Font.BOLD
 *      Font.ITALIC
 *      Font.BOLDITALIC</pre>
 * 
 * @param fontSize (Integer) The desired size of font.<br>
 * 
 * @return (Font) A Font Object
 */
public Font loadFont(String fontFilePath, int fontStyle, int fontSize) {
    Font font = null;
    int fontTypeResource = Font.TRUETYPE_FONT;
    if ((fontFilePath == null || fontFilePath.isEmpty()) || fontSize < 1) {
        throw new IllegalArgumentException("loadFont() Method Error! Arguments "
                + "passed to this method must contain a file path OR a numerical "
                + "value other than 0!" + System.lineSeparator());
    }
    String fileExt = (fontFilePath.contains(".") ? fontFilePath.substring(fontFilePath.lastIndexOf(".") + 1) : "");
    if (fontFilePath.isEmpty()) {
        throw new IllegalArgumentException("loadFont() Method Error! An illegal "
                + "font file has been passed to this method (no file name "
                + "extension)!" + System.lineSeparator());
    }
    
    switch (fileExt.toLowerCase()) {
        case "fot":
        case "t2":
        case "otf":
        case "ttf":
            fontTypeResource = Font.TRUETYPE_FONT;
            break;
        // PostScript/Adobe
        case "lwfn":
        case "pfa":
        case "pfb":
        case "pdm":
            fontTypeResource = Font.TYPE1_FONT;
            break;
        default:
            fontTypeResource = Font.TRUETYPE_FONT;
    }
    
    try {
        font = Font.createFont(fontTypeResource, new FileInputStream(
               new File(fontFilePath))).deriveFont(fontStyle, fontSize);
    }
    catch (FileNotFoundException ex) {
        Logger.getLogger("loadFont()").log(Level.SEVERE, null, ex);
    }
    catch (FontFormatException | IOException ex) {
        Logger.getLogger("loadFont()").log(Level.SEVERE, null, ex);
    }
    return font;
}

以及如何使用它：

JLabel jLabel_1 = new JLabel("This is my Label Caption");

/* Assumes the .ttf file in within the application's project 
   directory. Use a getResource() mechanism when loading from
   a resource directory.                           */
Font gameFont = loadFont("Retro Gaming.ttf", Font.BOLD, 18);

jLabel_1.setFont(gameFont);
