I have this code...

System.out.print("Enter the stack integers side by side with a space in between: ");
StringTokenizer st=new StringTokenizer(br.readLine());
int a[]=new int[9000];
int i=0;
do
{   
    a[i]=Integer.parseInt(st.nextToken());
    i++;
}while(st.hasMoreTokens());

When I print the elements in the array it prints me nothing. I tried to change datatype to String still the problem persists. And when I change the condition in the do...while loop I get only half of the elements given in the input when I print the array.
