title: what is wrong with this piece of code. keeps printing null
body: <p>I want to read each line from a file and store each line into an array of strings  </p>
  
  <pre><code>while ((line = br.readLine()) != null) {
  
              int i = 0;
  
              String[] sArray = new String[line.length()];
              sArray[i] += line;
              System.out.println(sArray[i]);
  
                     i++;
          }
  </code></pre>
  
  <p>output:   </p>
  
  <pre><code>nullKNZAVM   
  nullCPKCCA  
  nullKMUAXP
  </code></pre>
  
  <p>why it prints null before each set of letters.</p>
