将yyyy-MM-dd中的String Date转换为Java UtilDatein格式yyyy-MM-dd [重复]

Question

This question already has an answer here:

• want current date and time in “dd/MM/yyyy HH:mm:ss.SS” format 8 answers
• return date type with format in java [duplicate] 1 answer

I want to take a date value as String in the format yyyy-MM-dd and return a jabva util date in the same format. for this I am using below code , but the result is coming as "Wed Sep 18 00:00:00 CEST 2013"

    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
    String  strdate = "2013-09-18";
    Date utilDate = sdf.parse(strdate);
    System.out.println(utilDate);

Do i need to consider the locale also ? Please help to achieve this. Thanks in advance

Answer 1

Please try below code. You also have to format your simpleDateFormat object and pass utilDate object inside it to create formatted date as specified by you.

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DateTest {

     public static void main(String[] args) throws ParseException{
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
            String  strdate = "2013-09-18";
            Date utilDate = sdf.parse(strdate);
            String date=sdf.format(utilDate );
            System.out.println(date);
 }
}

We can also implement through Java8 like below:

import java.text.ParseException;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;

public class DateTest {

     public static void main(String[] args) throws ParseException{
         String  strdate = "2013-09-18";
            DateTimeFormatter formatter=DateTimeFormatter.ofPattern("yyyy-MM-dd");
            LocalDate date = LocalDate.parse(strdate, formatter);
            System.out.println(date.format(formatter));
}

}

or you can also use only LocalDate to change in java util like below.

import java.time.LocalDate;

public class TestCircle {

    public static void main(String args[]){
        String  strdate = "2013-09-18";
        LocalDate date = LocalDate.parse(strdate);
        System.out.println(date);
    }

}
