@ankitagupta17,
Thank you for your patience.

  1. Please check whether the font is actually installed on the OS. You can see all fonts using the following code:
    public void PrintFonts() {
        GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
        for (java.awt.Font font : ge.getAllFonts()) {
            System.out.println(font.getName());
            try {
                Object font2D = null;
                try {
                    font2D = Class.forName("sun.font.FontUtilities").getDeclaredMethod("getFont2D", new Class[]{java.awt.Font.class})
                            .invoke(null, new Object[]{font});
                } catch (Throwable ignored) {
                    try {
                        font2D = Class.forName("sun.font.FontManager").getDeclaredMethod("getFont2D", new Class[]{java.awt.Font.class})
                                .invoke(null, new Object[]{font});
                    } catch (Throwable e) {
                    }
                }
                java.lang.reflect.Field platNameField = Class.forName("sun.font.PhysicalFont").getDeclaredField("platName");
                platNameField.setAccessible(true);
                if (font2D != null) {
                    System.out.println(platNameField.get(font2D));
                }
            } catch (Throwable e) {
            }
        }
    }

  1. Check whether the font is available for your application. You can try to read the font file.

  2. If the font is not installed on the OS, then alternatively, you can load the font in the application runtime as below:

    String[] folders = new String[] { "path_to_a_folder_with_fonts" };
    FontsLoader.loadExternalFonts(folders);
