An immutable copy of a LocalDateTime where the required duration is added to it can be obtained using the plus() method in the LocalDateTime class in Java. This method requires two parameters i.e. the duration to be added and the TemporalUnit of the duration. Also, it returns the LocalDateTime object with the required duration added to it.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; import java.time.temporal.*; public class Demo {    public static void main(String[] args) {       LocalDateTime ldt = LocalDateTime.now();       System.out.println("The LocalDateTime is: " + ldt);       ...

An immutable copy of a LocalDateTime where the required duration is subtracted from it can be obtained using the minus() method in the LocalDateTime class in Java. This method requires two parameters i.e. the duration to be subtracted and the TemporalUnit of the duration. Also, it returns the LocalDateTime object with the required duration subtracted from it.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; import java.time.temporal.*; public class Demo {    public static void main(String[] args) {       LocalDateTime ldt = LocalDateTime.now();       System.out.println("The LocalDateTime is: " + ldt);       ...

The LocalDateTime instance can be obtained from a string value using the parse() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the string which is to be parsed. This string cannot be null. Also, it returns the LocalDateTime instance obtained from the string value that was passed as a parameter.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);    } }OutputThe LocalDateTime is: 2019-02-18T23:15:30Now ...

The LocalDateTime object can be queried as required using the query method in the LocalDateTime class in Java. This method requires a single parameter i.e. the query to be invoked and it returns the result of the query.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; import java.time.temporal.*; 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);       String precision = ldt.query(TemporalQueries.precision()).toString();       System.out.println("The Precision for the LocalDateTime is: "+ precision);    } }OutputThe LocalDateTime ...

The current date-time can be obtained from the system clock in the default time zone using the now() method in the LocalDateTime class in Java. This method requires no parameters and it returns the current date-time from the system clock in the default time zoneA 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 LocalDateTime is: " + ldt);    } }OutputThe LocalDateTime is: 2019-02-18T06:04:31.369Now let us understand the above program.The current date-time is obtained from ...

The difference between two LocalDateTime objects can be obtained using the until() method in the LocalDateTime class in Java. This method requires two parameters i.e. the end date for the LocalDateTime object and the Temporal unit. Also, it returns the difference between two LocalDateTime objects in the Temporal unit specified.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; import java.time.temporal.*; public class Demo {    public static void main(String[] args) {       LocalDateTime ldt1 = LocalDateTime.parse("2019-02-18T23:15:30");       LocalDateTime ldt2 = LocalDateTime.parse("2019-02-19T12:21:30");       System.out.println("The first LocalDateTime is: " + ldt1);     ...

The range of values for a ChronoField can be obtained using the range() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the ChronoField for which the range of values is required and it returns the range of values.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; import java.time.temporal.ChronoField; import java.time.temporal.ValueRange; public class Main {    public static void main(String[] args) {       LocalDateTime ldt = LocalDateTime.parse("2019-02-18T11:19:50");       System.out.println("The LocalDateTime is: " + ldt);       ValueRange dowRange = ldt.range(ChronoField.DAY_OF_WEEK);       System.out.println("The range of DAY_OF_WEEK: ...

An immutable copy of a LocalDateTime object where some seconds are added to it can be obtained using the plusSeconds() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the number of seconds to be added and it returns the LocalDateTime object with the added seconds.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 5 seconds added is: ...

An immutable copy of a LocalDateTime object where some days are added to it can be obtained using the plusDays() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the number of days to be added and it returns the LocalDateTime object with the added days.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 10 days added is: ...

An immutable copy of a LocalDateTime object where some months are added to it can be obtained using the plusMonths() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the number of months to be added and it returns the LocalDateTime object with the added months.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 5 months added is: ...
