Java 中的 OffsetDateTime isAfter()方法,带示例

原文:https://www . geesforgeks . org/offsetdatetime-is after-method-in-Java-with-examples/

Java 中 OffsetDateTime 类的isaafter()方法检查这个日期是否在指定的日期时间之后,如果是,返回 true。

语法:

public boolean isAfter(OffsetDateTime other)

参数:该方法接受单个参数其他,检查该日期时间是否在另一个日期时间之后。

返回值:如果在另一个日期时间之后,则返回真,否则返回假。

以下程序说明了 isAfter() 方法:

程序 1:

// Java program to demonstrate the isAfter() method

import java.time.OffsetDateTime;
import java.time.ZonedDateTime;

public class GFG {
    public static void main(String[] args)
    {

        // Parses the date1
        OffsetDateTime date1
            = OffsetDateTime
                  .parse("2018-12-12T13:30:30+05:00");

        // Parses the date2
        OffsetDateTime date2
            = OffsetDateTime
                  .parse("2018-12-12T13:30:30+05:00");

        // Prints both dates
        System.out.println("Date1: "
                           + date1);
        System.out.println("Date2: "
                           + date2);

        // Compare both
        System.out.println("Is Date1 after Date2? "
                           + date1.isAfter(date2));
    }
}

输出:

Date1: 2018-12-12T13:30:30+05:00
Date2: 2018-12-12T13:30:30+05:00
Is Date1 after Date2? false

程序二 :

// Java program to demonstrate the isAfter() method

import java.time.OffsetDateTime;
import java.time.ZonedDateTime;

public class GFG {
    public static void main(String[] args)
    {

        // Parses the date1
        OffsetDateTime date1
            = OffsetDateTime
                  .parse("2018-12-12T13:30:30+05:00");

        // Parses the date2
        OffsetDateTime date2
            = OffsetDateTime
                  .parse("2015-12-12T13:30:30+05:00");

        // Prints both dates
        System.out.println("Date1: "
                           + date1);
        System.out.println("Date2: "
                           + date2);

        // Compare both
        System.out.println("Is Date1 after Date2? "
                           + date1.isAfter(date2));
    }
}

输出:

Date1: 2018-12-12T13:30:30+05:00
Date2: 2015-12-12T13:30:30+05:00
Is Date1 after Date2? true
