Java中YearMonth類的now(ZoneId zone)方法用於從指定時區的係統時鍾中獲取當前的year-month。句法:
public static YearMonth now(ZoneId zone)
參數:此方法接受monthsToAdd作為參數,代表要使用的區域ID。
返回值:此方法使用係統時鍾返回當前的year-month。
以下示例程序旨在說明Java中YearMonth的now(ZoneId zone)方法:
程序1:
// Java program to demonstrate
// YearMonth.now(ZoneId zone) method
import java.time.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// apply now(ZoneId zone) method
// of YearMonth class
YearMonth result
= YearMonth.now(
ZoneId.systemDefault());
// print both year and month
System.out.println("YearMonth:"
+ result);
}
}
輸出:
YearMonth:2020-05
程序2:
// Java program to demonstrate
// YearMonth.now(ZoneId zone) method
import java.time.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// apply now(ZoneId zone) method
// of YearMonth class
YearMonth result
= YearMonth.now(
ZoneId.systemDefault());
// print only year
System.out.println(
"Year:"
+ result.get(
ChronoField.YEAR));
}
}
輸出:
Year:2020
程序3:
// Java program to demonstrate
// YearMonth.now(ZoneId zone) method
import java.time.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// apply now(ZoneId zone) method
// of YearMonth class
YearMonth result
= YearMonth.now(
ZoneId.systemDefault());
// print only month
System.out.println(
"Month:"
+ result.get(
ChronoField.MONTH_OF_YEAR));
}
}
輸出:
Month:5
