plusTemporalAmount

plusTemporalAmount is a method in the Java programming language, specifically part of the java.time package introduced in Java 8. This method is used to add a specified amount of time to a Temporal object, which represents a date, time, or both. The Temporal object can be an instance of classes like LocalDate, LocalTime, LocalDateTime, or ZonedDateTime.

The plusTemporalAmount method takes a single argument of type TemporalAmount. This interface represents an amount of time, such as days, months, or years. The TemporalAmount interface is implemented by classes like Period and Duration. Period is used for date-based amounts (years, months, days), while Duration is used for time-based amounts (seconds, nanoseconds).

When plusTemporalAmount is called on a Temporal object, it returns a new Temporal object with the specified amount of time added. The original Temporal object remains unchanged, as Temporal objects are immutable. This method is particularly useful for performing date and time arithmetic in a clear and concise manner.

Here is an example of how plusTemporalAmount can be used:

LocalDate date = LocalDate.of(2023, 10, 1);

Period period = Period.ofMonths(3);

LocalDate newDate = date.plusTemporalAmount(period);

In this example, the date is October 1, 2023. The period is three months. The newDate will be January 1, 2024, which is the result of adding three months to the original date. The original date remains unchanged.
