java.time_Java JapaneseDate atTime()用法及代码示例

java.time.chrono.JapaneseDate类的atTime()方法用于将此JapaneseDate时间与本地时间相加，以产生相等的日期和时间。

用法:

public final ChronoLocalDateTime

atTime(LocalTime localTime)

参数：此方法将LocalTime类型的对象作为参数。返回值：该方法通过将此日文日期与传递的本地时间相加来返回Chrono本地日期时间。

下面是说明atTime()方法的示例：示例1：

Java

// Java program to demonstrate

// atTime() method

import java.util.*;

import java.io.*;

import java.time.*;

import java.time.chrono.*;

public class GFG {

public static void main(String[] argv)

{

try {

// creating and initializing

// JapaneseDate Object

JapaneseDate hidate

= JapaneseDate.now();

// creating and initializing

// TemporalAccessor object

LocalTime localtime

= LocalTime.now();

// getting Chrono Local date time

// by using atTime() method

ChronoLocalDateTime date

= hidate.atTime(localtime);

// display the result

System.out.println(

"Chrono LocalDateTime is:"

+ date);

}

catch (DateTimeException e) {

System.out.println(

"passed parameter can"

+ " not form a date");

System.out.println(

"Exception thrown:" + e);

}

}

}

输出

Chrono LocalDateTime is:Japanese Heisei 32-03-18T17:18:51.528

范例2：

Java

// Java program to demonstrate

// atTime() method

import java.util.*;

import java.io.*;

import java.time.*;

import java.time.chrono.*;

public class GFG {

public static void main(String[] argv)

{

try {

// creating and initializing

// JapaneseDate Object

JapaneseDate hidate

= JapaneseDate.now();

// creating and initializing

// TemporalAccessor object

LocalTime localtime

= LocalTime.of(8, 20);

// getting Chrono Local date time

// by using atTime() method

ChronoLocalDateTime date

= hidate.atTime(localtime);

// display the result

System.out.println(

"Chrono LocalDateTime is:"

+ date);

}

catch (DateTimeException e) {

System.out.println(

"passed parameter can"

+ " not form a date");

System.out.println(

"Exception thrown:" + e);

}

}

}

输出

Chrono LocalDateTime is:Japanese Heisei 32-03-18T08:20
