How to resolve the problem in for loop?

import java.math.*;
A = BigInteger('12345678934');
B = BigInteger('10');

for i =1:double(10)
    i = BigInteger('i');
    X(i) = i.multiply(A);
end

I'm facing the following error

Java exception occurred:

java.lang.NumberFormatException: For input string: "i"

at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)

at java.lang.Integer.parseInt(Integer.java:580)

at java.math.BigInteger.<init>(BigInteger.java:470)

at java.math.BigInteger.<init>(BigInteger.java:606)

How to resolve this issue?

Thanking in anticipation.

import java.math.*;
A = BigInteger('12345678934');
B = BigInteger('10');

for i =1:double(10)
    iB = BigInteger(i);
    X(i) = iB.multiply(A);
end

X(1), X(2), X(end)

ans =

12345678934


ans =

24691357868


ans =

123456789340

If i can reach more than 2^53 then you would need a slightly different approach.
