Question

我需要在公众假期期间阻止进入停车场系统，但我希望可以在现有方法内完成更多课程。我的问题是，在java中是否存在预定义的公共假日日期，并且可以在if状态或某种类型中使用，以防止在今天的日期与公共假日日期列表匹配时进入。

这是我现有的方法。你可以看一下周末，周六和周日的检查，两者都是公众休息日。但在英国有更多的日子，如银行假期，但我如何定义所有其余的日期。

public boolean checkHoliday(){
    Calendar cal = Calendar.getInstance();
    int dayOfWeek = cal.get(Calendar.DAY_OF_WEEK); 
    if (dayOfWeek == 1 || dayOfWeek == 7){
        return true;
    } else {
        return false;
    }
    /*add method for further holiday date check*/ 

}
