Infinite while loop in java
<p>I am new to Java.  I tried to extract employee data from a text file and store it in a collection.  I used Stringtokenizer to get the strings from the file, but in the second iteration, the while loop goes infinite; it won't come out of the while loop.  My code is:</p>

<pre><code>public class Reader1 {
    String a;
    int i = 0;
    int count = 0;
    int x = 0;
    int y = 0;
    File f = new File(
            "C:\\Documents and Settings\\kmoorthi\\Desktop\\ak\\sample.txt");

    ArrayList&lt;Employee&gt; al = new ArrayList&lt;Employee&gt;();

    public void notePad() throws IOException {

        try {
            FileReader fis = new FileReader(f);
            BufferedReader br = new BufferedReader(fis);

            do {
                a = br.readLine();
                i++;
                if (i &gt; 1) {
                    if (a != null) {
                        StringTokenizer st = new StringTokenizer(a, "    ");
                        Employee e = new Employee();
                        System.out.println("hai1");
                        while (st.hasMoreTokens()) // here became infinite
                        {

                            count++;
                            if (count == 1) {

                                e.ename = st.nextToken();
                                al.add(e);

                            }

                            if (count == 2) {

                                e.eno = st.nextToken();
                                al.add(e);

                            }

                        }
                    }
                }
            } while (a != null);
            br.close();

        } catch (FileNotFoundException q) {
            q.printStackTrace();

        }
    }

    public void retrieve() {
        Iterator&lt;Employee&gt; it = al.iterator();
        while (it.hasNext()) {
            Employee fi = (Employee) it.next();
            String en = fi.ename;
            System.out.println(en);
        }
    }

    public static void main(String s[]) throws IOException {
        Reader1 r = new Reader1();
        r.notePad();
        r.retrieve();
    }
}
</code></pre>

<p>Please suggest a solution.</p>
