In this article, we will learn how to convert String to Date in Java using different date formats
Q) What is the need of converting String to Date ?
- Generally, whenever we receive any data from web application then it is passed in the form of String only
- But for further processing we need to convert String to Date
- This article explains about String to Date conversion in different formats
- Note: Likewise, sometimes Date to String conversion is also required for reverse process
1. String to Date conversion in different formats:
We will use below formats to convert String to Date
- dd/MM/yyyy
- dd-MM-yyyy
- dd.MM.yyyy
- dd MM yyyy
- MM dd, yyyy
- dd-MMM-yyyy
- E, MMM dd yyyy
- E, MMM dd yyyy HH:mm:ss
- E, MMM dd yyyy hh:mm:ss a
Note: for creating above formats we need mainly 2 classes
2. String to Date conversion examples :
2.1 Convert String to Date in (dd/MM/yyyy) format :
StringToDateFormat1.java
package in.bench.resources.date.conversion;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class StringToDateFormat1 {
public static void main(String[] args) throws ParseException {
// date in String
String strDate = "23/04/2021";
// formatter
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
// parse date in String format using above formatter
Date date = dateFormat.parse(strDate);
// print to console
System.out.println("Original String :- " + strDate);
System.out.println("\nConverted Date after formatting :- " + date);
}
}
Output:
Original String :- 23/04/2021
Converted Date after formatting :- Fri Apr 23 00:00:00 IST 2021
2.2 Convert String to Date in (dd-MM-yyyy) format :

// date in String
String strDate = "23-04-2021";
// formatter
DateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
// parse date in String format using above formatter
Date date = dateFormat.parse(strDate);
// print to console
System.out.println("Original String :- " + strDate);
System.out.println("\nConverted Date after formatting :- " + date);
}
}
Output:
