How to get a Date from year, month and day in Java?
Using the of() method
The of() method of the java.time.LocalDate class accepts the values of the year, month, and day of month as parameters, creates and returns an object of the LocalDate.
Example
import java.time.LocalDate;
public class Test {
public static void main(String[] args) {
LocalDate date = LocalDate.of(2014, 9, 11);
System.out.println("Date Value: "+date);
}
}Output
Date Value: 2014-09-11
Using the GregorianCalendar class
One of the constructors of the java.util.GregorianCalendar class accepts the values of year, month and day of month as values and creates a Calendar object representing it.
Example
import java.util.*;
class Test {
public static void main(String args[]){
//Creating a calendar object
Calendar cal = new GregorianCalendar(2020, 07, 18);
int day = cal.get(Calendar.DAY_OF_MONTH);
int month = cal.get(Calendar.MONTH);
int year = cal.get(Calendar.YEAR);
System.out.println("Day: " + day);
System.out.println("Month: " + month);
System.out.println("Year: " + year);
}
}Output
Day: 18 Month: 7 Year: 2020
Using the SimpleDateFormat object
One of the constructors of this class accepts a String value representing the desired date format and creates SimpleDateFormat object. To parse/convert a string as a Date object −
- Instantiate this class by passing desired format string.
- Parse the date string using the parse() method.
Example
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class Sample {
public static void main(String args[]) throws ParseException {
String date_string = "2007-25-06";
//Instantiating the SimpleDateFormat class
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-dd-MM");
//Parsing the given String to Date object
Date date = formatter.parse(date_string);
System.out.println("Date value: "+date);
}
}Output
Date value: Mon Jun 25 00:00:00 IST 2007
