we are developing a application which need to check whether user entering valid "AADHAR" number or not. i find some links and some "apis" but didn't meet final requirement please provide me a some useful material to solve this
What is Aadhaar?
Aadhaar is a 12 digit individual identification number issued by the Unique Identification Authority of India on behalf of the Government of India.
I think you are looking for Verhoeff algorithm,because UIDAI uses this algorithm for validating the aadhar number.You just need to create and use below class.
class VerhoeffAlgorithm{
static int[][] d = new int[][]
{
{0, 1, 2, 3, 4, 5, 6, 7, 8, 9},
{1, 2, 3, 4, 0, 6, 7, 8, 9, 5},
{2, 3, 4, 0, 1, 7, 8, 9, 5, 6},
{3, 4, 0, 1, 2, 8, 9, 5, 6, 7},
{4, 0, 1, 2, 3, 9, 5, 6, 7, 8},
{5, 9, 8, 7, 6, 0, 4, 3, 2, 1},
{6, 5, 9, 8, 7, 1, 0, 4, 3, 2},
{7, 6, 5, 9, 8, 2, 1, 0, 4, 3},
{8, 7, 6, 5, 9, 3, 2, 1, 0, 4},
{9, 8, 7, 6, 5, 4, 3, 2, 1, 0}
};
static int[][] p = new int[][]
{
{0, 1, 2, 3, 4, 5, 6, 7, 8, 9},
{1, 5, 7, 6, 2, 8, 3, 0, 9, 4},
{5, 8, 0, 3, 7, 9, 6, 1, 4, 2},
{8, 9, 1, 6, 0, 4, 3, 5, 2, 7},
{9, 4, 5, 3, 1, 2, 6, 8, 7, 0},
{4, 2, 8, 6, 5, 7, 3, 9, 0, 1},
{2, 7, 9, 3, 8, 0, 6, 4, 1, 5},
{7, 0, 4, 6, 9, 1, 3, 2, 5, 8}
};
static int[] inv = {0, 4, 3, 2, 1, 5, 6, 7, 8, 9};
public static boolean validateVerhoeff(String num){
int c = 0;
int[] myArray = StringToReversedIntArray(num);
for (int i = 0; i < myArray.length; i++){
c = d[c][p[(i % 8)][myArray[i]]];
}
return (c == 0);
}
private static int[] StringToReversedIntArray(String num){
int[] myArray = new int[num.length()];
for(int i = 0; i < num.length(); i++){
myArray[i] = Integer.parseInt(num.substring(i, i + 1));
}
myArray = Reverse(myArray);
return myArray;
}
private static int[] Reverse(int[] myArray){
int[] reversed = new int[myArray.length];
for(int i = 0; i < myArray.length ; i++){
reversed[i] = myArray[myArray.length - (i + 1)];
}
return reversed;
}
}
