Java 中的 OffsetTime atDate()方法，带示例

原文:https://www . geeksforgeeks . org/offsettime-at date-method-in-Java-with-examples/

Java 中 OffsetTime 类的 atDate() 方法将这个时间和一个日期结合起来，创建一个 OffsetDateTime。

语法:

public OffsetDateTime atDate(LocalDate date)

参数:该方法接受单个参数日期，指定要组合的日期，不为空。

返回值:返回由该时间和指定日期组成的偏置日期时间，不为空

下面的程序说明了 atDate()方法:

程序 1 :

// Java program to demonstrate the atDate() method

import java.time.LocalDate;
import java.time.OffsetDateTime;
import java.time.OffsetTime;

public class GFG {
    public static void main(String[] args)
    {
        // parses the current date
        LocalDate date = LocalDate.now();
        System.out.println("Current date: " + date);

        // Parses the current time
        OffsetTime time = OffsetTime.parse("11:10:10+06:03");
        OffsetDateTime datetime = time.atDate(date);
        System.out.println("Current date and time: " + datetime);
    }
}

输出:

Current date: 2018-12-31
Current date and time: 2018-12-31T11:10:10+06:03

程序二 :

// Java program to demonstrate the atDate() method

import java.time.LocalDate;
import java.time.OffsetDateTime;
import java.time.OffsetTime;

public class GFG {
    public static void main(String[] args)
    {
        // parses the current date
        LocalDate date = LocalDate.now();
        System.out.println("Current date: " + date);

        // Parses the current time
        OffsetTime time = OffsetTime.parse("12:15:14+16:03");
        OffsetDateTime datetime = time.atDate(date);
        System.out.println("Current date and time: " + datetime);
    }
}

输出:

Current date: 2018-12-31
Current date and time: 2018-12-31T12:15:14+16:03
