Reading String for list of Integers separated by spaces

Question

Trying to convert a string, like "21 42 8 7 51" into an Integer array --> [21] [42] [8] etc...

    list = "21 42 8";
    String[] splitArray = list.split(" ");
    int[] intArray = new int[splitArray.length]; 
    for (int i = 0; i < splitArray.length; i++){
        intArray[i] = Integer.parseInt(splitArray[i]);
    }


    for (int k = 0; k<intArray.length; k++){
        System.out.println(intArray[k]);
    }

The code is what I have written so far, and when I print what is supposed to be my Integer array, it only prints the first index

`yourString.split(" ")` will return you an array which contains the numbers — Nico T, Aug 11 '16 at 06:36
You want to create a **nested array** of dimentions `21 x 42 x 8 x 7 x 51` from that `String`? — fabian, Aug 11 '16 at 06:44
It's not very clear what result you want to achieve. Is it the string `"[21] [42] [8] [7] [51]"`, the array `{21, 42, 8, 7, 51}` or, as fabian said, a nested array of dimensions 21 x 42 x 8 x 7 x 51 ? Please rephrase the question so it is made clear, thank you. — Ray O'Kalahjan, Aug 11 '16 at 06:51
The end result would be an Integer array containing the numbers. — David Kane, Aug 11 '16 at 06:55
After your edit, your question is not a question anymore. You have a requirement, you have some code, but what is the problem? — RealSkeptic, Aug 11 '16 at 07:04
@DavidKane Cannot reproduce this. for me it prints all 3 ints in their own line... — fabian, Aug 11 '16 at 07:23
