下面是说明now()方法的示例:
示例 1:
Java
// Java program to demonstrate now() method
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] argv)
{
try {
// Creating and initializing ZoneId
ZoneId id = ZoneId.systemDefault();
// Creating and initializing
// JapaneseDate Object
JapaneseDate hidate
= JapaneseDate.now(id);
// Display the result
System.out.println("JapaneseDate: "
+ hidate);
}
catch (DateTimeException e) {
System.out.println("passed parameter can"
+ " not form a date");
System.out.println("Exception thrown: "
+ e);
}
}
}
