How to Convert java.util.Date to java.sql.Date in Java?

Conundrum in Conversion: From java.util.Date to java.sql.Date

While utilizing a java.util.Date as an input source for a query, it may arise that a java.sql.Date is required instead. However, the inability to perform implicit or explicit conversions between these two data types poses a challenge, especially for those new to the Java API.

Fear not, the quest for conversion has been answered!

To effectively transform a java.util.Date into its java.sql.Date counterpart, employ the following code:

import java.util.Date;
import java.sql.Date;

public class ConversionMagic {

  public static void main(String[] args) {
    Date utilDate = new Date();
    java.sql.Date sqlDate = new java.sql.Date(utilDate.getTime());
    System.out.println("Initial java.util.Date: " + utilDate);
    System.out.println("Transformed java.sql.Date: " + sqlDate);
  }

}

This snippet encapsulates the conversion process, where the constructor of java.sql.Date expects the millisecond representation of the java.util.Date as its input.

The example output verifies the conversion:

Initial java.util.Date: Tue Aug 09 11:38:11 GMT+08:00 2022
Transformed java.sql.Date: 2022-08-09
