Detailed explanation of the technical principles of the "PH verification" framework in the Java library

The "PH verification" framework in the Java class library is a technology that is used to verify and handle the number of resident ID numbers in Taiwan.This framework is based on national standard GB 11643-1999. It determines its effectiveness by verifying the legality of the ID number and provides some additional operating functions. The technical principles of the "pH verification" framework are as follows: 1. Verify the length of the ID number: First, check the length of the ID number by checking the length of the ID number to ensure that it is the correct Taiwan resident ID number.The standard Taiwan ID number should be 10 bits. 2. Verify the regional code represented by the first two: Next, the framework will determine the area of the ID number based on the first two digits.According to GB 11643-1999, the first two digits of the Taiwan ID number correspond to the specific region. 3. Verify birthday date format: By analyzing the annual, month, and day information in the ID number, verify whether it meets the legal date format to ensure the correctness of the birthday. 4. Verification sequence code: According to the standard of GB 11643-1999, the penultimate to the sixth place in the countdown of the Taiwan resident ID number is the sequential code for citizens in the region.The framework will verify the legitimacy of the order code. 5. Verify the school inspection code: The last one of the Taiwanese resident ID number is the verification code to verify the effectiveness of the entire ID number.The framework will calculate the school code and verify its correctness. In addition to the verification function, the framework also provides some additional operating functions, such as: 1. Get gender: By analyzing the order code in the ID number, the framework can determine the gender of the holder. 2. Get birthday date: The framework can extract the birthday information in the ID number. 3. Get regional information: According to the regional code represented by the previous two digits, the framework can obtain relevant information in the area of the ID number. Below is a simple Java code example, demonstrating how to use the "PH verification" framework to verify the effectiveness of the Taiwanese resident ID number: import com.example.phvalidation.PHValidator; public class Main { public static void main(String[] args) { String idNumber = "A123456789"; PHValidator validator = new PHValidator(); boolean isValid = validator.isValidIdNumber(idNumber); if (isValid) { System.out.println("Valid ID number."); } else { System.out.println("Invalid ID number."); } } } In the above example, we introduced a class called "PHVALIDATOR", which is the core component of the "PH verification" framework.We create a new instance and use the `ISVALIDIDIDNUMBER` method to verify the effectiveness of the ID number.If you return `true`, it means that the ID number is valid.Otherwise, return `false`. In short, the "PH verification" framework follows the national standard GB 11643-1999, and uses a series of verification steps to verify and handle the Taiwanese resident ID number.This framework not only supports the validity of the verification ID number, but also provides some additional functions to facilitate developers to process and extract information in the ID number.
