java.time.DayOfWeek的valueOf()方法是Java中的内置函数,该函数接收字符串,并返回与该字符串对应的DayOfWeek实例。该字符串必须与用于声明此类型的day-of-week常数的标识符完全匹配。不允许使用多余的空格字符。
方法声明:
public static DayOfWeek valueOf(String name)
用法:
DayOfWeek dayOfWeekObject = DayOfWeek.valueOf(String name)
参数:此方法将名称作为参数,其中:
- name–是字符串,它是day-of-week的名称。
- dayOfWeekObject–是DayOfWeek的实例。
返回值:该函数返回与名称字符串相对应的DayOfWeek实例
以下示例程序旨在说明上述方法:
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());
}
}
输出:
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());
}
}
输出:
SATURDAY
