How to get the date  datattype from sql database to java??? 
so far I have use this code but failed to fetch the date.  
import java.sql.*;//this is my import file
     String search="select * from tblflight";//select all data from my table
     ResultSet rs=stmt.executeQuery(search);//puting result in temporary var
     while(rs.next())
{
   Date d_time=rs.getDate("date_time");//getting result
   combo_box.addItem(d_time);//n showing error here while putting the date var here
}

A:

You have two options.  
 1 - Take sql date object and construct utils date using the getTime method of sql date
or
2 - call getTimeStamp instead of getDate , It will return object of sql timeStamp class that is actually child class of java.util. Date
1 -  Date d1 = new Date(rs.getDate("date_time").getTime());
2 -  Date d2 = rs.getTimestamp("date_time");
