java.time.DayOfWeek的valueOf()方法是Java中的內置函數,該函數接收字符串,並返回與該字符串對應的DayOfWeek實例。該字符串必須與用於聲明此類型的day-of-week常數的標識符完全匹配。不允許使用多餘的空格字符。
方法聲明:
public static DayOfWeek valueOf(String name)
用法:
DayOfWeek dayOfWeekObject = DayOfWeek.valueOf(String name)
參數:此方法將名稱作為參數,其中:
- name–是字符串,它是day-of-week的名稱。
- dayOfWeekObject–是DayOfWeek的實例。
返回值:該函數返回與名稱字符串相對應的DayOfWeek實例
以下示例程序旨在說明上述方法:
示例1:
// Java Program Demonstrate valueOf()
// method of DayOfWeek
import java.time.*;
class DayOfWeekExample {
public static void main(String[] args)
{
// Initializing a DayOfWeek instance
DayOfWeek dayOfWeek
= DayOfWeek.valueOf("MONDAY");
// Printing the day-of-week
System.out.println(dayOfWeek.name());
}
}
輸出:
MONDAY
示例2:
// Java Program Demonstrate valueOf()
// method of DayOfWeek
import java.time.*;
class DayOfWeekExample {
public static void main(String[] args)
{
// Initializing a DayOfWeek instance
DayOfWeek dayOfWeek
= DayOfWeek.valueOf("SATURDAY");
// Printing the day-of-week
System.out.println(dayOfWeek.name());
}
}
輸出:
SATURDAY
