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 想法来装箱,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视频类和公共静态实例,但是 netbeans IDE 向我提示“通过公共 API 导出非公共类型”。那么,我是否应该忽略这一点并继续按照我的方式做,或者如果你能建议我你的想法会很棒吗?
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;

System.err.println("Unknown video key: " + key);
break;
