Java程序获取星期几作为字符串

要获取星期几作为字符串，首先让我们显示当前日期-

LocalDate currentDate = LocalDate.now();

现在，使用DayOfWeek从当前日期获取星期几-

DayOfWeek day = currentDate.getDayOfWeek();

获取星期几作为字符串-

String weekName = day.name();

示例

import java.time.DayOfWeek;
import java.time.LocalDate;
public class Demo {
   public static void main(String[] args) {
      LocalDate currentDate = LocalDate.now();
      System.out.println("Current Date = "+currentDate);
      DayOfWeek day = currentDate.getDayOfWeek();
      int weekVal = day.getValue();
      String weekName = day.name();
      System.out.println("Week Number = "+weekVal);
      System.out.println("Week Name = "+weekName);
   }
}

输出结果

Current Date = 2019-04-12
Week Number = 5
Week Name = FRIDAY
