測試:
public static void main(String[] args) throws Exception { String idcard15 = "370283790911703";//15位 String idcard18 = "37078119790127719x";//18位 IdcardValidator ie15 = new IdcardValidator(idcard15); IdcardValidator ie18 = new IdcardValidator(idcard18); System.out.println(ie15.toString()); System.out.println(ie18.toString()); }
結果:
