Java JapaneseDate atTime()用法及代碼示例

java.time.chrono.JapaneseDate類的atTime()方法用於將此JapaneseDate時間與本地時間相加，以產生相等的日期和時間。

用法:

public final ChronoLocalDateTime
      atTime(LocalTime localTime)

參數：此方法將LocalTime類型的對象作為參數。返回值：該方法通過將此日文日期與傳遞的本地時間相加來返回Chrono本地日期時間。

下麵是說明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<JapaneseDate> 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);
        }
    }
}
