import java.util.Calendar;
public class FirstDay {
private static final String prefix="星期";
private static final String days="日一二三四五六";
public static String getWeekday(){
Calendar cd=Calendar.getInstance();
cd.set(Calendar.DATE, 1);
return prefix+days.charAt(cd.get(Calendar.DAY_OF_WEEK)-1);
}
public static void main(String[] args) {
String weekday=FirstDay.getWeekday();
System.out.println(weekday);
