Import to String, convert to Array...

in Programming Questions • 2 years ago

All I'm looking to do is import numerical data from a text file and store said data in an int array. I know to do that I have to first import them into a string, which I'm doing in setup, so all I really need to know is how to take that loaded string data and put it into an int array.

I would also appreciate it if someone could explain the required code, I'm a bit of a noob at Processing and I find that it helps if it's explained.

Thanks for your time.

depending on what your textfile looks like, you could do similar to this:

// this could be your imported string
String numbers_as_string = "1, 2, 3, 4, 5";
// split the string by the delimiter "," then trim the string array (delete spaces) and convert the trimmed string array to an integer array
int numbers_as_integer_array[] = int(trim(numbers_as_string.split(",")));
// print the final array
println(numbers_as_integer_array);
