我正在创建一个 Slick2D 游戏。现在，我正在创建一个 Video 类，其中包含内部类(FrameSize、FPS、FullScreen..)。所以我有一个 OOD 想法以一种方式进行包装，就像我们调用 System.out.println() 一样。这意味着我将拥有他的内部类的公共(public)视频类和公共(public)静态实例，但是 netbeans IDE 向我提示“通过公共(public) API 导出非公共(public)类型”。那么，我是应该忽略它并继续按照我的方式做，还是如果你能向我提出你的想法就太好了？

视频

public class Video {

    public static FrameSize frameSize;
    public static FullScreen fullScreen;
    public static FPS fps;

    private Video() {}

    public static void loadArguments(Scanner loadInput) {
        boolean isVideo = false;
        String readLine;

        while (loadInput.hasNext()) {
            readLine = loadInput.next();
            if (readLine.equalsIgnoreCase("video")) {
                isVideo = true;
                break;
            }
        }

        while (isVideo && loadInput.hasNext()) {
            readLine = loadInput.next();
            if (readLine.equalsIgnoreCase("end")) {
                break;
            }
            String[] line = readLine.split("=");

            String key = line[0];
            String value = line[1];

            switch (key) {
                case "width":
                    frameSize.setWidth(Integer.parseInt(value));
                    break;
                case "height":
                    frameSize.setHeight(Integer.parseInt(value));
                    break;
                case "fullscreen":
                    break;
                case "fps":
                    break;
                default:
                    System.err.println("Unknown video key: " + key);
                    break;
            }
        }
    }

    public static void saveArguments(String filePath) {
        Scanner saveInput;
        try {
            saveInput = new Scanner(new File(filePath));
        } catch (FileNotFoundException fne) {
            System.err.println("Invalid settings-file.");
            return;
        }

        // TO DO: save function

        saveInput.close();
    }

    class FrameSize {

        public final int[][] SIZE_VALUES = {
                {800, 600},
                {1000, 700},
                {1200, 800},
                {1400, 900}
        };

        private int index;
        private int width, height;

        private FrameSize() {}

        public void setSize(int width, int height) {
            this.width = width;
        }

        public int getWidth() {
            return width;
        }

        public void setWidth(int width) {
            this.width = width;
        }

        public int getHeight() {

        }

        public void setHeight(int height) {
            this.height = height;
        }

        @Override
        public String toString() {
            return this.width + " x " + this.height;
        }

    }

    class FullScreen {

        private boolean fullScreen;

        private FullScreen() {}

        public boolean isFullScreen() {
            return fullScreen;
        }

        public void setFullScreen(boolean fullScreen) {
            this.fullScreen = fullScreen;
        }

        @Override
        public String toString() {
            return "" + fullScreen;
        }        
    }

        private boolean FPS;

        private FPS() {}

    }

            }
        }

        while (isAudio && loadInput.hasNext()) {
