How to convert String to Date Time format in Java

In this tutorial we are going to see how to convert String to Date Time format using SimpleDateFormat.
1. 12-10-2013 12:02:35 PM format to Util Date Time

package com.javatutorialscorner.util;

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

public class StringToDateConvertion {

 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  
  SimpleDateFormat dateFormat = null;
  String inputDate = "12-10-2013 12:02:35 PM";
  
  try {
   dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss a");
   Date utilDate = dateFormat.parse(inputDate);
   System.out.println("Util Date : "+utilDate);
   String dateString = dateFormat.format(utilDate);
   System.out.println("Date String : "+dateString);
   
  } catch (ParseException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  

 }

}

Output

Util Date : Sat Oct 12 12:02:35 IST 2013

Date String : 12-10-2013 12:02:35 PM

2. 12-10-2013 12:02:35 format to Util Date Time

package com.javatutorialscorner.util;

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

public class StringToDateConvertion {

 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  
  SimpleDateFormat dateFormat = null;
  String inputDate = "12-10-2013 12:02:35";
  
  try {
   dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
   Date utilDate = dateFormat.parse(inputDate);
   System.out.println("Util Date : "+utilDate);
   String dateString = dateFormat.format(utilDate);
   System.out.println("Date String : "+dateString);
   
  } catch (ParseException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  

 }

}

Output

Util Date : Sat Oct 12 12:02:35 IST 2013

Date String : 12-10-2013 12:02:35

3. Sat,12-10-2013 12:02:35 format to Util Date Time

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

public class StringToDateConvertion {

 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  
  SimpleDateFormat dateFormat = null;
  String inputDate = "Sat,12-10-2013 12:02:35";
  
  try {
   dateFormat = new SimpleDateFormat("E,dd-MM-yyyy HH:mm:ss");
   Date utilDate = dateFormat.parse(inputDate);
   System.out.println("Util Date : "+utilDate);
   String dateString = dateFormat.format(utilDate);
   System.out.println("Date String : "+dateString);
   
  } catch (ParseException e) {
   // TODO Auto-generated catch block

  }
  

 }

}

Output

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

public class StringToDateConvertion {

 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  
  SimpleDateFormat dateFormat = null;
  String inputDate = "Saturday,12-10-2013 12:02:35";
  
  try {
   dateFormat = new SimpleDateFormat("EEEE,dd-MM-yyyy HH:mm:ss");
   Date utilDate = dateFormat.parse(inputDate);
   System.out.println("Util Date : "+utilDate);
   String dateString = dateFormat.format(utilDate);
   System.out.println("Date String : "+dateString);
   
  } catch (ParseException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  

 }

}

Output

Util Date : Sat Oct 12 12:02:35 IST 2013

Date String : Saturday,12-10-2013 12:02:35

5. SQL supported Date Time format

package com.javatutorialscorner.util;

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

public class StringToDateConvertion {

 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  
  SimpleDateFormat dateFormat = null;
  String inputDate = "2013-10-31 12:22:35";
  
  try {
   dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
   Date utilDate = dateFormat.parse(inputDate);
   System.out.println("Util Date : "+utilDate);
   String dateString = dateFormat.format(utilDate);
   System.out.println("Date String : "+dateString);
   
  } catch (ParseException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  

 }

}

Output

Util Date : Thu Oct 31 12:22:35 IST 2013

Date String : 2013-10-31 12:22:35
