  1. POJava: Reading a file, first line missing
    text
    copied!<p>I have an <code>HashMap&lt;String, String&gt;</code> which keeps the filename and the display name of an image. I read a file line by line and add the key and values to HashMap.</p> <pre><code>BufferedReader reader; String line; String[] lineSplit; HashMap&lt;String, String&gt; imenaZnaki = new HashMap&lt;String, String&gt;(); try { reader = new BufferedReader(new InputStreamReader(am.open("znaki_imena.txt"), "UTF-8")); line = reader.readLine(); while (line != null) { lineSplit = line.split("-&gt;"); imenaZnaki.put(lineSplit[0], lineSplit[1]); line = reader.readLine(); } reader.close(); } catch (IOException e) { e.printStackTrace(); } </code></pre> <p>Everything works as expected, except for the first added entry, the <code>.get(key)</code> returns null and <code>.containsKey(key)</code> returns false. All the other key/values work and are properly stored in the HashMap.</p> <p><strong>EDIT:</strong></p> <p>This makes no sense at all... After I added the content to HashMap I runned the code that MagicMan provided to check if all the entrys are inside the HashMap</p> <pre><code>for(String key: imenaZnaki.keySet()) { System.out.println("KEY: " + key + " VALUE: " + imenaZnaki.get(key)); } </code></pre> <p>And if I would <kbd>CTRL + F</kbd> for "nevar_andrej" it would show me 4 outputs, which is correct. But if I searched for " nevar_andrej" (with a whitespace) it would only show 3 of them, which is wrong, because the first one would be missing. So my guess is, that there is something in the first line of the file that causes confusion. So I added a dummy/fake first line (bla_bla->Bla bla) and it works, but it is a nasty workaround.</p> <p>This is my full text file that is encoded with UTF-8 <a href="http://pastebin.com/6A4r4jm6" rel="nofollow">http://pastebin.com/6A4r4jm6</a></p>
