Two LocalDateTime objects can be compared using the compareTo() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the LocalDateTime object to be compared.If the first LocalDateTime object is greater than the second LocalDateTime object it returns a positive number, if the first LocalDateTime object is lesser than the second LocalDateTime object it returns a negative number and if both the LocalDateTime objects are equal it returns zero.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 ...

An instance of a LocalDateTime object can be obtained from a Temporal object using the from() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the Temporal object and it returns the LocalDateTime object that is obtained from the Temporal object.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Main {    public static void main(String[] args) {       LocalDateTime ldt = LocalDateTime.from(ZonedDateTime.now());       System.out.println("The LocalDateTime is: " + ldt);    } }OutputThe LocalDateTime is: 2019-02-18T09:55:05.489Now let us understand the above program.The instance of the LocalDateTime ...

An immutable copy of a LocalDateTime with the month altered as required is done using the method withMonth() in the LocalDateTime class in Java. This method requires a single parameter i.e. the month that is to be set in the LocalDateTime and it returns the LocalDateTime with the month 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);       LocalDateTime ldt2 = ldt1.withMonth(7);       ...

An immutable copy of a LocalDateTime with the minutes altered as required is done using the method withMinute() in the LocalDateTime class in Java. This method requires a single parameter i.e. the minute that is to be set in the LocalDateTime and it returns the LocalDateTime with the minute 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);       LocalDateTime ldt2 = ldt1.withMinute(45);       ...

An immutable copy of a LocalDateTime object where some minutes are added to it can be obtained using the plusMinutes() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the number of minutes to be added and it returns the LocalDateTime object with the added minutes.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.now();       System.out.println("The current LocalDateTime is: " + ldt);       System.out.println("The LocalDateTime with 15 minutes added is: ...

An immutable copy of a LocalDateTime with the hour altered as required is done using the method withHour() in the LocalDateTime class in Java. This method requires a single parameter i.e. the hour that is to be set in the LocalDateTime and it returns the LocalDateTime with the hour 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);       LocalDateTime ldt2 = ldt1.withHour(5);       ...

An immutable copy of a LocalDateTime object where some hours are added to it can be obtained using the plusHours() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the number of hours to be added and it returns the LocalDateTime object with the added hours.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.now();       System.out.println("The current LocalDateTime is: " + ldt);       System.out.println("The LocalDateTime with 3 hours added is: ...

An immutable copy of a LocalDateTime with the day of year altered as required is done using the method withDayOfYear() in the LocalDateTime class in Java. This method requires a single parameter i.e. the day of year that is to be set in the LocalDateTime and it returns the LocalDateTime with the day of 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);       LocalDateTime ...

It can be checked if two LocalDateTime objects are equal or not using the isEqual() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the LocalDateTime object that is to be compared. It returns true if the two LocalDateTime objects are equal and false otherwise.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");       LocalDateTime ldt2 = LocalDateTime.parse("2019-02-18T23:15:30");       System.out.println("The LocalDateTime ldt1 is: " + ldt1);       System.out.println("The ...

It can be checked if a particular LocalDateTime is before the other LocalDateTime in a timeline using the isBefore() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the LocalDateTime object that is to be compared. It returns true if the LocalDateTime object is before the other LocalDateTime object and false otherwise.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("2019-02-15T11:37:12");       LocalDateTime ldt2 = LocalDateTime.parse("2019-02-18T23:15:30");       System.out.println("The LocalDateTime ldt1 is: ...
