java - How to put two numbers separated by a space into two different arrays -

i have 2 number inputs

1010 212

i want put these 2 different arrays ([1 0 1 0] , [2 1 2])

this code

import java.io.*; import java.util.*;  public class solution {      public static void main(string[] args) {         int array[] = new int[8];         int array2[] = new int[8];         int = 0;         scanner getnumber = new scanner(system.in);        {             array[i] = getnumber.nextint();              i++;        } while(getnumber.hasnextint());               system.out.println(arrays.tostring(array));      } } 

but output

[1010, 212, 0, 0, 0, 0, 0, 0]

(i put 8 generic array length because java compiler forced initialize each array)

you need store numbers first initialize arrays based on length of number. can length turning string. once left number , empty array, can split integer array of digits number of ways.

int[] array, array2; scanner in = new scanner(system.in);  int a, b;  = in.nextint(); b = in.nextint();  array = new int[integer.tostring(a).length()]; array2 = new int[integer.tostring(b).length()];  int = 0; while(a > 0) {     array[i] = % 10;     /= 10;     i++; }  i=0; while(b > 0) {     array2[i] = b % 10;     b /= 10;     i++; }  system.out.println(arrays.tostring(array)); system.out.println(arrays.tostring(array2));
