- Java code
import java.util.*;public class CalendarTest{ public static void main(String[] args){ GregorianCalendar d = new GregorianCalendar(); int today = d.get(Calendar.DAY_OF_MONTH); int month = d.get(Calendar.MONTH); d.set(Calendar.DAY_OF_MONTH,1); int weekday = d.get(Calendar.DAY_OF_MONTH); System.out.println("Sun Mon Tue Wed Thu Fri Sat"); for(int i = Calendar.SUNDAY; i < weekday; i++) System.out.print(" "); do{ int day = d.get(Calendar.DAY_OF_MONTH); System.out.printf("%3d",day); if(day == today) System.out.println("*"); else System.out.println(" "); if(weekday == Calendar.SATURDAY) System.out.println(); d.add(Calendar.DAY_OF_MONTH,1); weekday = d.get(Calendar.DAY_OF_MONTH); }while (d.get(Calendar.MONTH) == month); if(weekday != Calendar.SUNDAY) System.out.println(); }}我想输出 类似这样的
Sun Mon Tue Wed Thu Fri Sat
1 2 3 ..
但是这段代码是一竖列呀-。- 求解哪里不对！
------解决方案--------------------
你这有俩问题
第一 是当天的加×号，但是不应该换行
第二 应该是 int weekday = d.get(Calendar.DAY_OF_WEEK); 此处有俩地方
即一周当中的天数 而不是一月中的天数
把这两个改好了就好了
