get - Extract numbers from a string?! Java -

for program trying figure how can go taking series of number string entered user; extract each number @ spaces , parse them integers.

p.s still newbie programming languages please explain in way can understand, thanks.

this have far:

a user may input series of number this: 15 31 94 87 108 11 7 63 79

public int [] getnumbers (){      scanner reader = new scanner (system.in);      string inputstr = reader.nextline();      int[] = new int [10];     string[] numb = new string [10];      int space = inputstr.indexof (" ");     int length = inputstr.length();       (int x = 0; x < numb.length; x++){          numb [x] = inputstr.substring (0, space);          inputstr = inputstr.substring (space+1);          int num = integer.parseint (numb[x]);         system.out.println (num);         a[x] = num;     }     return a; } 

this @ moment first number, shorten string. how go finding next number , ending out having going out of bound ? thank you.

you can using string's split method:

string[] numbers = numb.split(" "); int[] = new int [numbers.length];  (int x = 0; x < numb.length; x++){         a[x] = integer.parseint (numbers[x]);; }
