Methods:

public LocalDateTime minus(TemporalAmount amountToSubtract)

This method returns a new instance of LocalDateTime subtracted by provided TemporalAmount.

There are two implementations of TemporalAmount provided in JSE: Duration and Period.


public LocalDateTime minus(long amountToSubtract,

                           TemporalUnit unit)

This method returns a new instance of LocalDateTime , subtracted by the provided amount per provided TemporalUnit.



Examples


package com.logicbig.example.localdatetime;

import java.time.LocalDateTime;
import java.time.Period;

public class MinusExample {

    public static void main (String... args) {
        LocalDateTime d = LocalDateTime.of(2016, 11, 12,
                                           12, 30, 15);
        LocalDateTime d2 = d.minus(Period.ofDays(15));
        System.out.println(d2);
    }
}

Output

package com.logicbig.example.localdatetime;

import java.time.Duration;
import java.time.LocalDateTime;

public class MinusExample2 {

        LocalDateTime d = LocalDateTime.of(2016, 11, 12,
                                           12, 30, 15);
        LocalDateTime d2 = d.minus(Duration.ofMillis(200000));
        System.out.println(d2);

        d2 = d.minus(Duration.ofDays(200));
        System.out.println(d2);

    }
