Obviously it helps if you know how many numbers you're going to get so
you don't have to extend your array at run time. But sometimes you
don't,sigh.
The simplest answer is brute force:
char[] line = new char[TheLongestLineYoullEverGet];
double[] buf = new double[AsManyLinesAsYoureGoingToRead];
int count = 0;
while (efficientlyReadALineIntoCharArray(line))
{
double n = 0;
n = // brute-force parse perl regex /-?\d*\.\d*[eE]\d*/
if (count == buf.length)
// grow the buffer
buffer[count++] = n;
}
