首先,显示当前日期:
LocalDate date = LocalDate.now();
现在,从上述日期(当前日期)中获取星期几:
DayOfWeek day = DayOfWeek.of(date.get(ChronoField.DAY_OF_WEEK));
根据上述结果,使用SWITCH检查当天。如果一天是星期六/周日,则为周末。
import java.time.DayOfWeek; import java.time.temporal.ChronoField; import java.time.LocalDate; public class Demo { public static void main(String[] argv) { LocalDate date = LocalDate.now(); DayOfWeek day = DayOfWeek.of(date.get(ChronoField.DAY_OF_WEEK)); switch (day) { case SATURDAY: System.out.println("Weekend - Saturday"); case SUNDAY: System.out.println("Weekend - Sunday"); default: System.out.println("Not a Weekend"); } } }
输出结果
Not a Weekend
