Difference between java.sql.Date and java.util.Date

The d/w java.util.date and java.sql is miner diffrence. The java.util.date is return the date with time and date and sql.date is return data with is retrive the data entry date i.e whitch time the data has enry or not.

hi Rajan,how r u ? your answer for the difference between java.util.Date & java.sql.Date is not understandable.so please give more information about that.thanking you suresh.

java.sql.Date stores only date information, not times. Simply converting a java.util.Date into a java.sql.Date will silently set the time to midnight.

Hi

1) java.util.Date is the superclass for java.sql.Date i.e public class Date extends java.util.Date { }

2) java.sql.Date is used for databases where we just need to store date and not time but java.util.date returns Date as well as time

3) java.util.Date has constructor with 0 parameters but java.sql.Date does not has the one, so we canot use new Date() here, time in milliseconds needs to be passed

Hi,friends,the answer is not clear enough.please send the correct data and maintain the uniquenees.if u don't know please don't answer.thanks!!

Hi java.util.Date contains many methods.This class extends java.lang.object implements java.io.Serializable,java.lang.Cloneable, java.lang.Comparableit can contains both bean properties are also availablewhere as the java.sql.Date-------------- java.sql.Date extends java.util.Date {

Hi Friends,

This is the main difference

java.util.date ---------->dd mm yyyy hh:mm:ss

java.sql.date----------->dd mm yyyy hh:mm:ss: ms

ok bye..........

Hi,

This was exact output about java.util.Date and java.sql.Date:

  java.util.Date date1 = new java.util.Date();
  System.out.println("Hello World! "+ date1);
  
  java.sql.Date date2 = new java.sql.Date(date1.getTime());
  System.out.println("Hello World! "+ date2);

java.util.Date ----> here date1 object prints date and time.

java.sql.Date ----> here date2 object prints only date (2006-11-30)

Thanks,

Srinadh

1. The java.sql.Date stores only day, month and year.
2. The java.util.Date stores day, month, year along with time information upto milliseconds accuracy.

the sql versions are namely:
1. java.sql.Date - having only date information
2. java.sql.Time - having only time information
3. java.sql.TimeStamp - having date + time information with nanoseconds precision.

These are created as a wrapper for SQL DATE, TIME, TIMESTAMP datatypes which the java.util.Date is inefficient to handle.

java.sql.Date - Used mainly while storing in the database

java.sql.date is not a date time, means it does not stored time, only it stores date.

But java.util.Data store long, date and time both.

Explanation: public class ((java.util.Date extends java.lang.Object)) implements java.io.Serializ able,java.lang.Cloneable,java.lang.Comparable

java.sql.Date extends the java.uti.Date cls obj so java.sql.Date is the subclass of java.util.Date

mainly java.sql.Date are used for jdbc application to insert date value into dbtable......Date value cannot insert directly............follow some steps

1)end user reads the date in string format
2)after reads the date it convert into util.Date cls obj
3)after completion of 2nd step again util.Date cls obj convert into java.sql.Date cls obj........it is the way to print the date in the dbtable as column................ to better understand see the following code..............................

Code
import java.sql.*;
import java.util.*;
import java.text.*;
class DateDemo3
{
        public static void main(String[] args)  throws Exception
        {
                
        
                Scanner sc=new Scanner(System.in);
                System.out.println("enter the dob");
                String dob=sc.next();
                SimpleDateFormat sdf=new SimpleDateFormat("MM-dd-yy");
        java.util.Date ud=sdf.parse(dob);
                long msdob=ud.getTime();//according to the echo standrard since jan 1970 it counts to till date and gives the difference
 
        java.sql.Date sqdob=new java.sql.Date(msdob);
                System.out.println(sqdob);
 
 
        
        }
}
 

java.util.date is used to show date and time of the system

java.sql.date is used to show the date of retrieved data from database and also it shows entered date to database
