Java_实现身份证信息提取个人信息

1.身份证提起出生年月信息
注意：有15位和18位

public String idCard2Birthday(String no) {
		String birthday = "";
		if (no.length() == 15) {
			String tempYear = no.substring(6, 8);
			String tempMonth = no.substring(8, 10);
			String tempDate = no.substring(10, 12);

			int tempCYear = Calendar.getInstance().get(Calendar.YEAR);
			tempYear = "20" + tempYear;
			int itempYear = Integer.parseInt(tempYear);
			if (itempYear > tempCYear) {
				tempYear = "19" + tempYear.substring(2);
			}
			birthday = tempYear + "-" + tempMonth + "-" + tempDate;
		} else if (no.length() == 18) {
			String tempYear = no.substring(6, 10);
			String tempMonth = no.substring(10, 12);
			String tempDate = no.substring(12, 14);
			birthday = tempYear + "-" + tempMonth + "-" + tempDate;
		}
		return birthday;
	}
