Java 기능의 플랫폼 간 호환성을 확인하는 방법은 무엇입니까?

String osName = System.getProperty("os.name");
String osArch = System.getProperty("os.arch");
System.out.println("操作系统：" + osName);
System.out.println("架构：" + osArch);

Method method = MyClass.class.getMethod("myFunction");
boolean isSupported = method.isAnnotationPresent(PlatformAnnotation.class);
if (isSupported) {
  PlatformAnnotation annotation = method.getAnnotation(PlatformAnnotation.class);
  String[] supportedPlatforms = annotation.value();
  // 检查当前平台是否在支持的列表中
}

public class FileManager {

  public void saveFile(String fileName, byte[] data) throws IOException {
    // 检查当前平台
    String osName = System.getProperty("os.name");
    if (osName.equals("Windows")) {
      // Windows 特定代码
      ...
    } else if (osName.equals("Linux")) {
      // Linux 特定代码
      ...
    } else {
      throw new UnsupportedOperationException("当前平台不受支持");
    }
  }

}
