java.time.DayOfWeek的of()方法是Java中的内置函数,它从int值返回DayOfWeek的实例。 int值的范围是1(星期一)至7(星期日)。
方法声明:
public static DayOfWeek of(int dayOfWeek)
用法:
DayOfWeek dayOfWeekObject = DayOfWeek.of(int dayOfWeek)
参数:此方法将dayOfWeek作为参数,其中:
- dayOfWeek–是从1(星期一)到7(星期日)的int值。
- dayOfWeekObject–是DayOfWeek对象的实例。
返回值:该函数返回DayOfWeek对象的实例。
以下示例程序旨在说明上述方法:
示例1:
// Java Program Demonstrate of()
// method of DayOfWeek
import java.time.DayOfWeek;
class DayOfWeekExample {
public static void main(String[] args)
{
// Getting an instance of DayOfWeek from int value
DayOfWeek dayOfWeek = DayOfWeek.of(4);
// Printing the day of the week
// and its Int value
System.out.println("Day of the Week - "
+ dayOfWeek.name());
System.out.println("Int Value of "
+ dayOfWeek.name() + " - "
+ dayOfWeek.getValue());
}
}
输出:
Day of the Week - THURSDAY Int Value of THURSDAY - 4
示例2:
// Java Program Demonstrate of()
// method of DayOfWeek
import java.time.DayOfWeek;
class DayOfWeekExample {
public static void main(String[] args)
{
// Getting an instance of DayOfWeek from int value
DayOfWeek dayOfWeek = DayOfWeek.of(7);
// Printing the day of the week
// and its Int value
System.out.println("Day of the Week - "
+ dayOfWeek.name());
System.out.println("Int Value of "
+ dayOfWeek.name() + " - "
+ dayOfWeek.getValue());
}
}
输出:
Day of the Week - SUNDAY Int Value of SUNDAY - 7
