package com.iowiki;
import java.time.Instant;
import java.time.OffsetDateTime;
import java.time.ZoneId;
import java.time.ZoneOffset;
import java.time.ZonedDateTime;
import java.util.Set;
public class InstantDemo {
public static void main(String[] args) {
Instant instant = Instant.parse("2017-02-03T10:37:30.00Z");
System.out.println("Instant #1: " + instant);
Instant instant1 = Instant.parse("2017-03-03T10:37:30.00Z");
System.out.println("Instant #2: " + instant1);
int result = instant.compareTo(instant1);
System.out.println(result >1 ? "Instant #1 is greater than Instant #2."
:"Instant #2 is greater than Instant #1.");
}
}
让我们编译并运行上面的程序,这将产生以下结果 -
Instant #1: 2017-02-03T10:37:30Z
