I want to insert current date into mysql database using android studio. And I am using volley library for insertion. Need hints only, not in detail. Can anyone help me?
Thanks in advance!
> You should try this one for getting current date:
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd");
String todate= dateFormat.format(currentdate());
String finalto = todate.toString(); //here you get current date
private Date currentdate() {
final Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, 0);
return cal.getTime();
}

Date format coming from the database: 1629777600000
SimpleDateFormat simpleDateFormatter = new SimpleDateFormat("MM/dd/yyyy");
simpleDateFormat.format(1629777600000);
When using this simple date format I am not able to convert 1629777600000 to a viewable date
SimpleDateFormat simpleDateFormatter = new SimpleDateFormat("MM/dd/yyyy");
System.out.println(simpleDateFormatter.format(1629777600000L));
Print: 08/24/2021
But your code does not compile:
you initialize simpleDateFormatter but use simpleDateFormat (without ter)
1629777600000 is a Long, therefore it needs an L at its end
I think the L problem is just from modifiying the code for the stackoverflow question. But the variable name is maybe a real problem in your code.

I want to get all the dates of a month in a list so i can show all the dates from that month on a JSF page. When the month changes the amount of dates has to change accordingly.
I Use Java 8 LocalDate.
How can i best do that?
I'm not sure how can one need to put all the dates of the month in a database, but here's a way to get the List of all the dates of the current month:
LocalDate date = LocalDate.now().withDayOfMonth(1);
LocalDate end = date.plusMonths(1);
List<LocalDate> dates = new ArrayList<>();
while(date.isBefore(end)) {
dates.add(date);
date = date.plusDays(1);
}

Date class has before, after and compareTo methods. See the Javadoc API. That should give you all you need.
java.util.Date API

I am creating a system using java in eclipse where the user is going to enter their expiry date (month and year only) when prompted. I will then need to perform a check to check whether this is valid: i.e the month and year entered is not before the current month and year.
I have tried searching on here and elsewhere but could only find solutions which would compare the day and/or time. Is there any way that I could compare only the month and year to the current date?
I'm relatively new to coding so apologies if this is actually quite simple.
Thanks
This code seems to have worked for me:
String input = keyboard.next();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/yy");
simpleDateFormat.setLenient(false);
Date expiry = simpleDateFormat.parse(input);
boolean expired = expiry.before(new Date());
if (expired == true)
{
System.out.println("This card has already expired");
}
