java.sql.Date

The java.sql.Date class represents the only date in Java. It inherits the java.util.Date class.

The java.sql.Date instance is widely used in the JDBC because it represents the date that can be stored in a database.

Some constructors and methods of java.sql.Date class has been deprecated. Here, we are not giving the list of any deprecated constructor and method.

java.sql.Date Constructor

No.	Constructor	Description
1)	Date(long milliseconds)	Creates a sql date object for the given milliseconds since January 1, 1970, 00:00:00 GMT.

java.sql.Date Methods

No.	Method	Description
1)	void setTime(long time)	changes the current sql date to given time.
2)	Instant toInstant()	converts current sql date into Instant object.
3)	LocalDate toLocalDate()	converts current sql date into LocalDate object.
4)	String toString()	converts this sql date object to a string.
5)	static Date valueOf(LocalDate date)	returns sql date object for the given LocalDate.
6)	static Date valueOf(String date)	returns sql date object for the given String.

java.sql.Date Example: get current date

Let’s see the example to print date in java using the java.sql.Date class.

FileName: SQLDateExample.java

  public class SQLDateExample {  public static void main(String[] args) {      long millis=System.currentTimeMillis();      java.sql.Date date=new java.sql.Date(millis);      System.out.println(date);  }  }  

Test it Now

Output:

2015-03-30

Java String to java.sql.Date Example

Let’s see the example to convert string into java.sql.Date using the valueOf() method.

FileName: StringToSQLDateExample.java

  import java.sql.Date;  public class StringToSQLDateExample {  public static void main(String[] args) {  String str=”2015-03-31″;  Date date=Date.valueOf(str);//converting string into sql date  System.out.println(date);  }  }  

Test it Now

Output:

2015-03-31

java.sql.Date Example: void setTime()

Let’s see the working of the setTime() method.

FileName: SetTimeExample.java

  // important import statements  import java.util.Calendar;  import java.util.Date;  public class SetTimeExample  {  // main method  public static void main(String[] argvs)  {  // A date object is created with the specified time.  Date d = new Date();  System.out.println(“Initial date is: ” + d);  // setting the time for 1000000 milliseconds after  // 01 January, 1970, 00:00:00 GMT.  d.setTime(1000000);  // Printing the time  System.out.println(“Date after the setting the time is: ” + d);  }  }  

Output:

Initial date is: Fri Nov 26 11:52:20 GMT 2021  Date after the setting the time is: Thu Jan 01 00:16:40 GMT 1970

java.sql.Date Example: void toLocalDate()

Let’s see the working of the toLocalDate() method.

FileName: ToLocalDateExample.java

  // important import statement  import java.util.*;  import java.time.*;  public class ToLocalDateExample   {  // main method  public static void main(String[] argvs)  {  // Getting the instance of LocalDateTime  LocalDateTime dtm = LocalDateTime.now();  // Getting the LocalDate representation of the LocalDateTime  // using the toLocalDate() method  System.out.println(“The date is: ” + dtm.toLocalDate());  }  }  

Output:

The date is: 2021-11-26

java.sql.Date Example: void toInstant()

Let’s see the working of the toInstant() method.

FileName: ToInstantExample.java

  // important import statement  import java.util.Calendar;  import java.util.Date;  import java.time.Instant;  public class ToInstantExample   {  // main method  public static void main(String argvs[])  {  // Creating an object of Calendar  // by invoking the getInstance method  Calendar cln = Calendar.getInstance();  // Setting the Month  // The months begin with 0. 0 means January  cln.set(Calendar.MONTH, 07);  // Setting Date  cln.set(Calendar.DATE, 12);  // Setting Year  cln.set(Calendar.YEAR, 2021);  // Creating an object of the class Date  // with the mentioned time.  Date d = cln.getTime();  Instant instt = d.toInstant();  System.out.println(“The original Date is: ” + d.toString());  System.out.println(“The instant is: ” + instt);  }  }  

Output:

The original Date is: Thu Aug 12 12:41:01 GMT 2021  The instant is: 2021-08-12T12:41:01.635Z
