I have a string like "2 -56 0 78 0 4568 -89..." end so on. Now I use Scanner.nextInt() to parse it, but it seems to be slow. Platform is Android. Any advices how to implement in for better speed?

Thanks.

Answer 1

use myString.split(" "), which split on ' ', then Integer.valuesOf(..)

Answer 2

Split the string on the space and parse each entry

for (String s: string.split(" ")) {
  int i = Integer.parseInt(s);
  //do something with i
}
