The atDate() method of OffsetTime class in Java combines this time with a date to create a OffsetDateTime.
Syntax :
public OffsetDateTime atDate(LocalDate date)
Parameter: This method accepts a single parameter date which specifies the date to combine with, not null.
Return Value: It returns the OffsetDateTime formed from this time and the specified date, not null
Below programs illustrate the atDate() method:
Program 1 :
// Java program to demonstrate the atDate() method  import java.time.LocalDate;import java.time.OffsetDateTime;import java.time.OffsetTime;  public class GFG {    public static void main(String[] args)    {        // parses the current date        LocalDate date = LocalDate.now();        System.out.println("Current date: " + date);          // Parses the current time        OffsetTime time = OffsetTime.parse("11:10:10+06:03");        OffsetDateTime datetime = time.atDate(date);        System.out.println("Current date and time: " + datetime);    }} |
Output:
Current date: 2018-12-31 Current date and time: 2018-12-31T11:10:10+06:03
Program 2 :
// Java program to demonstrate the atDate() method  import java.time.LocalDate;import java.time.OffsetDateTime;import java.time.OffsetTime;  public class GFG {    public static void main(String[] args)    {        // parses the current date        LocalDate date = LocalDate.now();        System.out.println("Current date: " + date);          // Parses the current time        OffsetTime time = OffsetTime.parse("12:15:14+16:03");        OffsetDateTime datetime = time.atDate(date);        System.out.println("Current date and time: " + datetime);    }} |
Output:
Current date: 2018-12-31 Current date and time: 2018-12-31T12:15:14+16:03
