如何用Java检查给定的日期是否代表周末
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。
示例
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
