Determine if date is weekday/weekend java
提问by Aidan Moore
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 :/
我试图让它比较一周中的哪一天，如果它是周末然后执行一个操作（尚未实施）但是如果我输入今天的日期 25/11/2016 或明天是星期六 26/ 11/2016，它仍然只打印“WEEKDAY”。它不起作用，我被卡住了：/
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");
}
}

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

In your if statement you forgot the c1.get on sunday. Should be like this:
在您的 if 语句中，您忘记了星期天的 c1.get。应该是这样的：
if (c1.get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY ||
c1.get(Calendar.DAY_OF_WEEK) == Calendar.SUNDAY)
Also why do you send in the boolean b and double c? It's never used.
另外你为什么要发送布尔值 b 和双 c？它从来没有使用过。

you can use calender.DayofWeek method to find which day it is
您可以使用 calender.DayofWeek 方法来查找今天是哪一天
Calendar cl = Calendar.getInstance();
c1.setTime(Enter Yor Date);
int day = c.get(Calendar.DAY_OF_WEEK);
if(check day value is 5 or 6)
{
// Weekend Coding
}
Else
{
// Weekday Coding
}
