LocalDateTime Class minusSeconds() method

• minusSeconds() method is available in java.time package.
• minusSeconds() method is used to subtract the given seconds from this date-time object and return the LocalDateTime.
• minusSeconds() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• minusSeconds() method may throw an exception at the time of performing subtraction.
  DateTimeException – This exception may throw when the calculated result value exceeds the limit.

Syntax:

    public LocalDateTime minusSeconds(long sec_val);

Parameter(s):

• long sec_val – represents the seconds to be subtracted from this LocalDateTime.

Return value:

The return type of this method is LocalDateTime, it returns the LocalDateTime that holds the value subtracted the given seconds from this LocalDateTime.

Example:

// Java program to demonstrate the example 
// of minusSeconds(long sec_val) method 
// of LocalDateTime

import java.time.*;

public class MinusSecondsOfLocalDateTime {
    public static void main(String args[]) {
        long seconds = 4;
        // Instantiates two LocalDateTime
        LocalDateTime da_ti1 = LocalDateTime.parse("2005-10-05T10:10:10.00");
        LocalDateTime da_ti2 = LocalDateTime.now();

        // Display da_ti1, da_ti2 and
        // seconds
        System.out.println("LocalDateTime da_ti1 and da_ti2: ");
        System.out.println("da_ti1: " + da_ti1);
        System.out.println("da_ti2: " + da_ti2);
        System.out.println("seconds to subtract: " + seconds);

        System.out.println();

        // Here, this method subtracts the given
        // seconds from this date-time object i.e.
        // here we are subracting 4 seconds from 
        // this object da_ti1
        LocalDateTime minus_sec = da_ti1.minusSeconds(seconds);

        // Display minus_sec
        System.out.print("da_ti1.minusSeconds(seconds): ");
        System.out.println(minus_sec);

        // Here, this method subtracts the given
        // seconds from this date-time object and 
        // i.e. here we are subracting 4 seconds from 
        // this object da_ti2
        minus_sec = da_ti2.minusSeconds(seconds);

        // Display minus_sec
        System.out.print("da_ti2.minusSeconds(seconds): ");
        System.out.println(minus_sec);
    }
}

Output

LocalDateTime da_ti1 and da_ti2: 
da_ti1: 2005-10-05T10:10:10
da_ti2: 2020-06-08T02:47:53.494821
seconds to subtract: 4

da_ti1.minusSeconds(seconds): 2005-10-05T10:10:06
da_ti2.minusSeconds(seconds): 2020-06-08T02:47:49.494821
