我正在尝试理解Java 8流.我有两节课:

public class UserMeal {
    protected final LocalDateTime dateTime;

    protected final String description;

    protected final int calories;

    public UserMeal(LocalDateTime dateTime, String description, int calories) {
        this.dateTime = dateTime;
        this.description = description;
        this.calories = calories;
    }

    public LocalDateTime getDateTime() {
        return dateTime;
    }

    public String getDescription() {
        return description;
    }

    public int getCalories() {
        return calories;
    }
}

和:

public class UserMealWithExceed {
    protected final LocalDateTime dateTime;

    protected final String description;

    protected final int calories;

    protected final boolean exceed;

    public …

Can't find error ((
