Question

After many calculations I have String containing binary representation of some data.
How to convert it into array of ints in a consistent way.

I can take every 32 bits and put it into array but it doesn’t seem like this solution.

Answer 1

Parsing each 32 bit section seems like a perfectly good solution to me. Note that it’s probably best to use Long to do the parsing, to avoid problems if the leading digit is 1. For example:

public static int[] parseBinaryToIntArray(String input) {
    // TODO: Validation
    int[] output = new int[input.length() / 32];
    for (int i = 0; i < output.length; i++) {
    String section = input.substring(i * 32, (i + 1) * 32);
        output[i] = (int) Long.parseLong(section, 2);
    }
    return output;
}
