java – How to get day,month,year from String date?

Posted by: admin June 15, 2020 Leave a comment

Questions:

I have a date on String, like this:

String date="25.07.2007";

And I want to divide it to:

String day;
String month;
String year;

What is the best way to do this?

How to&Answers:

One way to split a string in Java is to use .split(“regex”) which splits a string according to the pattern provided, returning a String array.

String [] dateParts = date.split(".");
String day = dateParts[0];
String month = dateParts[1];
String year = dateParts[2];

To get current date:
You can also change the format of the date by changing the values passed to SimpleDateFormat. Don’t forget the imports.

  DateFormat dateFormater = new SimpleDateFormat("dd/MM/yy HH:mm:ss");
  Date date = new Date();

Answer:

java.time

The modern way is to use the Android version of the back-port of the java.time framework built into Java 8 and later.

First, parse the input string into a date-time object. The LocalDate class represents a date-only value without time-of-day and without time zone.

String input = "25.07.2007";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern( "MM.dd.yyyy" );
LocalDate localDate = LocalDate.parse( input , formatter );

Now you can ask the LocalDate for its values.

int year = localDate.getYear();
int month = localDate.getMonthValue();
int dayOfMonth = localDate.getDayOfMonth();

You can use the handy Month enum to localize the name of the month.

String monthName = localDate.getMonth().getDisplayName( TextStyle.FULL , Locale.CANADA_FRENCH );

Answer:

Try this…

String dateArr[] = date.split(".");
String day = dateArr[0];
String month = dateArr[1];
String year = dateArr[2];

or

String day = date.substring(0,2);
String month = date.substring(3,5);
String year = date.substring(6,10);

To get the current date…

Date currentDate = Calendar.getInstance().getTime();

To get day, month and year from current date..

int day = currentDate.get(Calendar.DAY_OF_MONTH);
int month = currentDate.get(Calendar.MONTH);
int year = currentDate.get(Calendar.YEAR);

Month starts at 0 here…

Answer:

date.split(".") will not work
Split methods takes regex as parameter. For regex "." means any character. Instead we have to pass "\." as parameter.

String [] dateParts = date.split("\.");
String day = dateParts[0];
String month = dateParts[1];
String year = dateParts[2];

Answer:

public class DateTest {

    /**
     * @param args
     * @throws ParseException 
     */
    public static void main(String[] args) throws ParseException {
        String starDate = "7/12/1995 12:00:00 AM";
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy");
        String newDateStr = simpleDateFormat.format(simpleDateFormat.parse(starDate));
        String str[] = newDateStr.split("/");
        String month = str[1];
        String year = str[2];
    }

}
