StringTokenizer to read multiple lines

Question

I've been struggling to make my program to read multiple lines from the input text
input5.txt:
-.1 -2.3 -45.678 -90
.1 .23 .45678 .90
1 2.3 4.56
0
and the program will stop reading when it sees 0 in the line. What i got was a nullPointerException, it reads a single line fine, but when it comes to multiple lines, it messes up. Heres a portion of my program code:
while (info1 != null && !end)
     tokenizer = new StringTokenizer(info1, " \t\r\n");
     while ((info1 = stdin.readLine()) != null && info1.length() != 0)
          if (tokenizer.hasMoreTokens())
               // temp is a dummy String to help for counting limit.
               temp = tokenizer.nextToken();
               dummy [limit] = temp;
               limit++;
     numbers = new float [limit];
     while (count < limit)
          while (tokenizer2.hasMoreTokens() && num1 != 0.0 && num1 != 0)
               num1 = Float.parseFloat(dummy[count]);
               numbers[count] = num1;
               count++;
     end = true;
}

You need to move the "new StringTokenizer" into the following while loop
