本文介绍了如何在Android中验证伊朗梅利代码(国家代码或代码梅利)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我需要一种方法来验证伊朗人的Melli代码(国家代码或Melli代码).
I need a method to validate the Melli Code (National Code or Code Melli) of iranian people.
我知道它有一个公式.
推荐答案
此方法验证了伊朗人民的Melli码.
This method validates the Iranian people's Melli code.
public boolean validateMelliCode(String melliCode) {
String[] identicalDigits = {"0000000000", "1111111111", "2222222222", "3333333333", "4444444444", "5555555555", "6666666666", "7777777777", "8888888888", "9999999999"};
if (melliCode.trim().isEmpty()) {
Toast.makeText(getApplicationContext(), "Melli Code is empty", Toast.LENGTH_LONG).show();
return false; // Melli Code is empty
} else if (melliCode.length() != 10) {
Toast.makeText(getApplicationContext(), "Melli Code must be exactly 10 digits", Toast.LENGTH_LONG).show();
return false; // Melli Code is less or more than 10 digits
} else if (Arrays.asList(identicalDigits).contains(melliCode)) {
Toast.makeText(getApplicationContext(), "MelliCode is not valid (Fake MelliCode)", Toast.LENGTH_LONG).show();
return false; // Fake Melli Code
} else {
int sum = 0;
for (int i = 0; i < 9; i++) {
sum += Character.getNumericValue(melliCode.charAt(i)) * (10 - i);
}
int lastDigit;
int divideRemaining = sum % 11;
if (divideRemaining < 2) {
lastDigit = divideRemaining;
} else {
lastDigit = 11 - (divideRemaining);
}
if (Character.getNumericValue(melliCode.charAt(9)) == lastDigit) {
Toast.makeText(getApplicationContext(), "MelliCode is valid", Toast.LENGTH_LONG).show();
return true;
} else {
Toast.makeText(getApplicationContext(), "MelliCode is not valid", Toast.LENGTH_LONG).show();
return false; // Invalid MelliCode
}
}
}
更新
国家/地区代码,因此我们必须接受由重复数字组成的国家/地区代码.所以我们不需要这个数组:
UPDATE
This authentic news agency said there is a man who has "1111111111"
national code, so we have to accept the national codes composed of repetitive digits. So we don't need this Array:
String[] identicalDigits = {"0000000000", "1111111111", "2222222222", "3333333333", "4444444444", "5555555555", "6666666666", "7777777777", "8888888888", "9999999999"};
我们也不需要这部分条件:
and also we don't need this part of condition:
else if (Arrays.asList(identicalDigits).contains(melliCode)) {
Toast.makeText(getApplicationContext(), "MelliCode is not valid (Fake MelliCode)", Toast.LENGTH_LONG).show();
return false; // Fake Melli Code
}
