Use Java to determine whether a date is earlier or later than another date
Another common operation in work is how to determine whether a given date is greater than or less than a certain day sky? In Java 8, the LocalDate class has two methods isBefore() and isAfter() for comparing dates. When calling the isBefore() method, it returns true if the given date is less than the current date.
package com.shxt.demo02;
import java.time.LocalDate;
import java.time.temporal.ChronoUnit;
public class Demo11 {
public static void main(String[] args) {
LocalDate today = LocalDate.now();
LocalDate tomorrow = LocalDate.of(2018,2,6);
if(tomorrow.isAfter(today)){
System.out.println("之后的日期:"+tomorrow);
}
LocalDate yesterday = today.minus(1, ChronoUnit.DAYS);
if(yesterday.isBefore(today)){
System.out.println("之前的日期:"+yesterday);
}
}
