Java Language Tutorial => Convert java.util.Date to java.sql.Date

Example

java.util.Date to java.sql.Date conversion is usually necessary when a Date object needs to be written in a database.

java.sql.Date is a wrapper around millisecond value and is used by JDBC to identify an SQL DATE type

In the below example, we use the java.util.Date() constructor, that creates a Date object and initializes it to represent time to the nearest millisecond. This date is used in the convert(java.util.Date utilDate) method to return a java.sql.Date object

Example

public class UtilToSqlConversion {
    
    public static void main(String args[])
    {
        java.util.Date utilDate = new java.util.Date();
        System.out.println("java.util.Date is : " + utilDate);
        java.sql.Date sqlDate = convert(utilDate);
        System.out.println("java.sql.Date is : " + sqlDate);
        DateFormat df = new SimpleDateFormat("dd/MM/YYYY - hh:mm:ss");
        System.out.println("dateFormated date is : " + df.format(utilDate));
    }

    private static java.sql.Date convert(java.util.Date uDate) {
        java.sql.Date sDate = new java.sql.Date(uDate.getTime());
        return sDate;
    }

}

Output

java.util.Date is : Fri Jul 22 14:40:35 IST 2016
java.sql.Date is : 2016-07-22
dateFormated date is : 22/07/2016 - 02:40:35

java.util.Date has both date and time information, whereas java.sql.Date only has date information
