Java - array stuck in for loop -

-

i'm trying fill array keyboard input, method gets stuck on b = in.nextint(); line, in second last value want input. i'm confused.

 public static void main(string[] args) {          scanner in=new scanner(system.in);          int a_size;           int duplicate;           system.out.println("enter test size");          a_size = in.nextint();          int [] a_array;           a_array = new int[a_size];            int b;          (int i= 0; <a_array.length; i++ ){              system.out.println("enter number");               b = in.nextint();              a_array[i] = b;              }            system.out.println("passed");   }

edit: sorry kind folks. tested code , working fine. simple code , not see wrong it. apologize , agree bundle of sticks. please forgive me.
