Java判斷時間，Email,手機號,身份證等是否為正確格式

??????? *??????? 1、號碼的結構
???????? 公民身份號碼是特征組合碼，由十七位數字本體碼和一位校驗碼組成。排列順序從左至右依次為：六位數字地址碼，八位數字出生日期碼，三位數字順序碼和一位數字校驗碼。
??????? 2、地址碼(前六位數）
??????? 表示編碼對象常住戶口所在縣(市、旗、區(qū))的行政區(qū)劃代碼，按GB/T2260的規(guī)定執(zhí)行。
??????? 3、出生日期碼（第七位至十四位）
??????? 表示編碼對象出生的年、月、日，按GB/T7408的規(guī)定執(zhí)行，年、月、日代碼之間不用分隔符。
??????? 4、順序碼（第十五位至十七位）
??????? 表示在同一地址碼所標識的區(qū)域范圍內，對同年、同月、同日出生的人編定的順序號，順序碼的奇數分配給男性，偶數分配給女性。
??????? 5、校驗碼（第十八位數）
??????? （1）十七位數字本體碼加權求和公式
??????? S = Sum(Ai * Wi), i = 0, ... , 16 ，先對前17位數字的權求和
??????? Ai:表示第i位置上的身份證號碼數字值
??????? Wi:表示第i位置上的加權因子
??????? Wi: 7 9 10 5 8 4 2 1 6 3 7 9 10 5 8 4 2?
??????? （2）計算模
??????? Y = mod(S, 11)
??????? （3）通過模得到對應的校驗碼
??????? Y: 0 1 2 3 4 5 6 7 8 9 10
??????? 校驗碼: 1 0 X 9 8 7 6 5 4 3 2
??????? 所以我們就可以大致寫一個函數來校驗是否正確了。
