Java获取今天是周几

你可以使用Java中的Calendar类来获取今天是周几。以下是示例代码：

import java.util.Calendar;

public class Main {
  public static void main(String[] args) {
    Calendar calendar = Calendar.getInstance();
    int dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK);
    String[] weekDays = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
    System.out.println("Today is " + weekDays[dayOfWeek - 1]);
  }
}

这个程序将输出今天是星期几，例如：Today is Monday。
