Java 中的 OffsetDateTime withSecond()方法，示例

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

Java 中 OffsetDateTime 类的 withSecond() 方法返回这个 OffsetDateTime 的一个副本，其中的分钟数按照参数中的指定进行了更改。

语法:

public OffsetDateTime withSecond(int second)

参数:该方法接受单个参数秒，该参数指定要在结果中设置的分钟秒，范围从 0 到 59。

返回值:返回基于该日期的偏移日期时间，请求的分钟数不为空。

异常:当分钟秒数值无效时，程序抛出日期时间异常。

以下程序说明了带秒()的方法:

程序 1:

// Java program to demonstrate the withSecond() method

import java.time.OffsetDateTime;

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

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

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

        // Changes the second-of-minute
        System.out.println("Date1 after altering second-of-minute: "
                           + date1.withSecond(40));
    }
}

输出:

Date1: 2018-12-12T13:30:30+05:00
Date1 after altering second-of-minute : 2018-12-12T13:30:40+05:00

程序二:

// Java program to demonstrate the withSecond() method

import java.time.OffsetDateTime;

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

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

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

            // Changes the second-of-minute
            System.out.println("Date1 after altering second-of-minute: "
                               + date1.withSecond(70));
        }
        catch (Exception e) {
            System.out.println("Exception: " + e);
        }
    }
}

输出:

Date1: 2018-12-12T13:30:30+05:00
Exception: java.time.DateTimeException:
           Invalid value for SecondOfMinute (valid values 0 - 59): 70
