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

Live Demo

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

Live Demo

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
