Input: " 10 50 10 40 50 80 60 20 ". I want to convert it into string array then into int array. The problem is that when I split with space, it shows errors as:

1st string is " 10"
2nd string is " 50"
3rd string is "10"

Code:

s = line.split(" ");
for(i=0;i<8;i++)
{
    arr= Integer.parseInt(s[i]);
    System.out.println(arr);
}

I want it should only string array with no space

1st string is "10"
2nd string is "50"
3rd string is "10"

`arr= Integer.parseInt(s[i].trim());`. – SatyaTNV Feb 07 '16 at 11:43

`s = line.split("\\s+");` – Tunaki Feb 07 '16 at 11:44
@Tunaki. There's problem with your `split`, because it gets `""` at first position and causes `NumberFormatException` in for loop. – Matt Feb 07 '16 at 11:55
@user Well the OP's code is buggy. The split works correctly: it starts with spaces so, of course, there is going to be an empty string at the beginning. – Tunaki Feb 07 '16 at 12:01
