我已经完成我的代码，并且可以正确打印，但是我有一个测试器类，而我的类代码的某些部分却没有打印出应有的内容，请帮忙。我已经尝试了许多方法来修复它，但是它无法正常工作。
测试器类：
AsyncLoadingCache<Location, ClimaTempoLocale> localeWeatherCache =
Caffeine.newBuilder().buildAsync(location ->
climaTempoRepository.findLocaleByCityNameAndState(location.city(), location.state()));
AsyncLoadingCache<ClimaTempoLocale, CurrentWeather> currentWeatherCache =
Caffeine.newBuilder().buildAsync(climaTempoRepository::findCurrentWeatherByLocale);
AsyncLoadingCache<ClimaTempoLocale, WeatherForecasts> weatherForecastsCache =
Caffeine.newBuilder().buildAsync(climaTempoRepository::findDailyForecastByLocale);
public Mono<Weather> weatherForecastByLocation(Location location) {
var locale = Mono.fromFuture(localeWeatherCache.get(location));
var currentWeather = Mono.fromFuture(locale.map(localeWeatherCache::get));
var weatherForecasts = Mono.fromFuture(locale.map(weatherForecastsCache::get));
return Mono.zip(currentWeather, weatherForecasts, (current, forecasts) ->
Weather.buildWith(builder -> {
builder.location = location;
builder.currentWeather = current;
builder.weatherForecasts = forecasts;
}));
}
我这堂课有问题。

这是它的“打印”，因为您会看到一些与他们应打印的内容不匹配。

答案 0 :(得分：0)
isOpen(int time)的条件错误。您使用或||，而应使用和&&，否则，如果第一个条件为true，则不会检查第二个条件，因此将标记所有大于关闭时间的值确实如此。
将其更改为
public boolean isOpen(int currentTime)
{
if((currentTime >= opening) && (currentTime < closing))
{
return true;
}
else
{
return false;
}
}
案例1编写得不好。您正在尝试直接打印对象；它应该返回类似于对象实例代码的内容。您需要的是传递给toString方法的东西。而且，仅接收1个类型为String的参数的构造函数不会分配Type，而只分配打开和关闭。应该是
public Store(String type)
{
this.opening = 10;
this.closing = 21;
this.type = type;
}
