确定日期是工作日/周末java [英] Determine if date is weekday/weekend java

问题描述

我正在尝试比较星期几，如果是周末，请执行一项操作（尚未执行），但是如果我输入今天的日期25/11/2016或明天， 2016年11月26日星期六，它仍然只打印 WEEKDAY。它不起作用，我被卡住了：/

I'm trying to make it compare what day of the week it is and if it is a weekend then perform an action(not implemented yet) but if I put in today's date 25/11/2016 or tomorrows which is a Saturday 26/11/2016, it still only prints "WEEKDAY". Its not working and I'm stuck :/

public static void calcDatePrice(String a, boolean b, double c){
    System.out.println("CALC PRICE METHOD: " + a);
    Double price;
    Date d1 = new Date(a);

    Calendar c1 = Calendar.getInstance();
    c1.setTime(d1);
    System.out.println(c1.get(Calendar.DAY_OF_WEEK));

    if ((c1.get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY) 
            || (Calendar.DAY_OF_WEEK == Calendar.SUNDAY)) {  //or sunday   
    System.out.println("WEEKEND PRICE");
    }else {
    System.out.println("WEEKDAY");
    }
}

推荐答案

在您的if语句在星期天忘记了c1.get。应该是这样的：

In your if statement you forgot the c1.get on sunday. Should be like this:

if (c1.get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY || 
    c1.get(Calendar.DAY_OF_WEEK) == Calendar.SUNDAY)

为什么还要发送布尔b和双c？它从未使用过。

Also why do you send in the boolean b and double c? It's never used.
