The LocalDateTime can be formatted with the specified formatter using the format() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the LocalDateTime object to be formatted and it returns the formatted LocalDateTime with the specified formatter.A program that demonstrates this is given as follows −Example Live Demoimport java.util.*; import java.time.*; import java.time.format.DateTimeFormatter; public class Main {    public static void main(String[] args) {       LocalDateTime ldt = LocalDateTime.parse("2019-02-18T14:30:47");       System.out.println("The LocalDateTime is: " + ldt);       DateTimeFormatter dtf = DateTimeFormatter.ISO_TIME;       System.out.println("The formatted LocalDateTime is: " + ...

An immutable copy of a LocalDateTime with the year altered as required is done using the method withYear() in the LocalDateTime class in Java. This method requires a single parameter i.e. the year that is to be set in the LocalDateTime and it returns the LocalDateTime with the year altered as required.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Main { public static void main(String[] args) { LocalDateTime ldt1 = LocalDateTime.parse("2019-02-18T23:15:30"); System.out.println("The LocalDateTime is: " + ldt1); ...

The month of the year is obtained using getMonthValue() method in the LocalDateTime class in Java. This method requires no parameter and it returns the month of the year which may be in the range of 1 to 12.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { LocalDateTime ldt = LocalDateTime.parse("2019-02-18T23:15:30"); System.out.println("The LocalDateTime is: " + ldt); System.out.println("The month is: " + ldt.getMonthValue()); ...

The day of the month for a particular LocalDateTime can be obtained using the getDayOfMonth() method in the LocalDateTime class in Java. This method requires no parameters and it returns the day of the month which can be in the range of 1 to 31.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { LocalDateTime ldt = LocalDateTime.parse("2019-02-18T11:30:15"); System.out.println("The LocalDateTime is: " + ldt); System.out.println("The day of ...

The day of the week for a particular LocalDateTime can be obtained using the getDayOfWeek() method in the LocalDateTime class in Java. This method requires no parameters and it returns the day of the week.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { LocalDateTime ldt = LocalDateTime.parse("2019-02-18T11:30:15"); System.out.println("The LocalDateTime is: " + ldt); System.out.println("The day of the week is: " + ldt.getDayOfWeek()); } ...

The length of the year in a particular LocalDate is obtained using the method lengthOfYear() in the LocalDate class in Java. This method requires no parameters and it returns the length of the year in a particular LocalDate i.e. 365 or 366 for a leap year.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Main { public static void main(String[] args) { LocalDate ld = LocalDate.parse("2019-02-15"); System.out.println("The LocalDate is: " + ld); System.out.println("The length ...

The hash code value of the LocalDate can be obtained using the hashCode() method in the LocalDate class in Java. This method requires no parameters and it returns the hash code value of the LocalDate.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Main { public static void main(String[] args) { LocalDate ld = LocalDate.parse("2019-02-15"); System.out.println("The LocalDate is: " + ld); System.out.println("The hash code is: " + ld.hashCode()); } }OutputThe LocalDate ...
