OffsetDateTime minusYears() method in Java with examples

The minusYears() method of OffsetDateTime class in Java returns a copy of this OffsetDateTime with the specified number of years subtracted from the parsed date and time.

Syntax:

public OffsetDateTime minusYears(long years)

Parameter: This method accepts a single parameter years which specifies the years to be subtracted from the parsed date. It can be negative also, in that case, it adds the number of years to it.

Return Value: It returns an OffsetDateTime based on this date-time with the years subtracted and not null.

Exceptions: The program throws a DateTimeException when it exceeds the supported data and time range.

Below programs illustrate the minusYears() method:

Program 1:

// Java program to demonstrate the minusYears() method

import java.time.OffsetDateTime;
import java.time.ZonedDateTime;

public class GFG {
    public static void main(String[] args)
    {

        // Parses the date1
        OffsetDateTime date1
            = OffsetDateTime
                  .parse("2018-12-12T13:30:30+05:00");

        // Prints dates
        System.out.println("Date1: " + date1);

        // Subtracts the number of years
        System.out.println("Date1 after subtracting years: "
                           + date1.minusYears(-120));
    }
}

Output:

Date1: 2018-12-12T13:30:30+05:00
Date1 after subtracting years: 2138-12-12T13:30:30+05:00

Program 2 :

// Java program to demonstrate the minusYears() method

import java.time.OffsetDateTime;
import java.time.ZonedDateTime;

public class GFG {
    public static void main(String[] args)
    {

        // Parses the date1
        OffsetDateTime date1
            = OffsetDateTime
                  .parse("2018-12-12T13:30:30+05:00");

        // Prints dates
        System.out.println("Date1: "
                           + date1);

        // Subtracts the number of years
        System.out.println("Date1 after subtracting years: "
                           + date1.minusYears(140));
    }
}

Output:

Date1: 2018-12-12T13:30:30+05:00
Date1 after subtracting years: 1878-12-12T13:30:30+05:00
