Class:

Methods:

public LocalDate minus(TemporalAmount amountToSubtract)

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

There are two implementations of TemporalAmount provided in JSE: Duration and Period. Using an instance of Duration with this method will throw UnsupportedTemporalTypeException because Duration is the amount of time measured in terms of seconds and nanoseconds which is not supported by LocalDate.


public LocalDate minus(long amountToSubtract,

                       TemporalUnit unit)

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

This method will throw UnsupportedTemporalTypeException if the provided TemporalUnit is not supported by LocalDate, such as ChronoUnit.HOURS.


Examples


package com.logicbig.example.localdate;

import java.time.Duration;
import java.time.LocalDate;
import java.time.Month;
import java.time.Period;

public class MinusExample {

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