Calculate the number of days and months between two dates

A common date operation is to calculate the number of days, weeks, or months between two dates. In Java 8, you can use the java.time.Period class to do calculations.

In the following example, we calculate the number of months between today and a future day.

package com.shxt.demo02;  
import java.time.LocalDate;  
import java.time.Period;  
public class Demo15 {      
public static void main(String[] args) {          
LocalDate today = LocalDate.now();          
LocalDate java8Release = LocalDate.of(2018, 12, 14);          
Period periodToNextJavaRelease = Period.between(today, java8Release);          
System.out.println("Months left between today and Java 8 release : "                  + periodToNextJavaRelease.getMonths() );      
}  
}
