Java中OffsetDateTime类的withSecond()方法返回此OffsetDateTime的副本,其中second-of-minute如参数中所述进行了更改。
用法:
public OffsetDateTime withSecond(int second)
参数:此方法接受单个参数秒,该参数指定要在结果中设置的second-of-minute,其范围可以从0到59。
返回值:它基于此日期返回一个OffsetDateTime,并带有请求的second-of-minute,并且不为null。
异常:当second-of-minute值无效时,程序将引发DateTimeException。
以下示例程序旨在说明withSecond()方法:
示例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
示例2:
// 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
