i have some output in form:
some text: 1234 ms
some text: 345 ms
some text: 678 ms

i want to store these numbers into array.
my code:
while((s = br.readLine()) != null) {
                              if(s.contains("some text")){
                                    int i = Integer.parseInt(s.substring(34, 38));

int[] array = new int[1000];
int index = 0;
while((s = br.readLine()) != null) {
                              if(s.contains("some text")){
                                    int i = Integer.parseInt(s.substring(34, 38));
                                    System.out.println("i="+i);
                                    array[index++] = i;

i can print the 1234 as output but compiler throws error at next line 345.
Exception in thread "main" java.lang.NumberFormatException: For input string: "593 "

you could change that to:


                                    int i = Integer.parseInt(s.substring(34, 38).trim());

though thats only going to work for 3 or 4 digit numbers.
any other size will fail
