如何利用Java的DAY_OF_WEEK，来实现日期操作

【专家解说】：public static String getXQ(int year, int month, int day) { Calendar c = Calendar.getInstance(); c.set(year, month - 1, day); int i = c.get(Calendar.DAY_OF_WEEK); String s = "星期"; switch (i) { case 1: s = s + "日"; break; case 2: s = s + "一"; break; case 3: s = s + "二"; break; case 4: s = s + "三"; break; case 5: s = s + "四"; break; case 6: s = s + "五"; break; case 7: s = s + "六"; break; default: break; } return s; }
