    <p>The problem was with the wtf method. Your endless loop was in there when you wrote:</p> <pre><code>while(line==null){ bw.write(ltw); bw.newLine(); } </code></pre> <p>BufferedReader states it <code>returns null if the end of the stream has been reached.</code> Since your files are initially empty (I'm assuming), this will constantly be true, and you will continue writing new lines and your String.</p> <p>I was playing around with your code and rewrote it to something like this.</p> <pre><code>import java.util.*; import java.io.*; public class fread { public static void main (String[] args) { Scanner scan = new Scanner(System.in); String even = "2.txt"; String odd = "1.txt"; String line = ""; int lineNumber = 0; while (scan.hasNext() ) { line = scan.nextLine(); if (lineNumber++ % 2 == 1) writeText(even, line); else writeText(odd, line); } } static void writeText(String filename, String ltw) { try { BufferedWriter bw = new BufferedWriter(new FileWriter(filename, true)); bw.write(ltw); bw.newLine(); bw.close(); } catch ( IOException e) { e.printStackTrace(); } } } </code></pre> <p>It uses input redirection, so typing <code>java fread &lt; database.txt</code> will give you your results, however this only does appends to a file. If your files do not exist, or are initially empty, this will work as you expect. You'll have to specify this code to the needs of the program. Regardless, you should be able to take my writeText method and incorporate it into your program to be able to to get yours working.</p>

    1. COWell it truly does the work but have a small problem implementing the reader. Can I use a code that will immediately process "java fread < database.txt" without the need to type it into the console?

    2. CO@VitalijKornijenko You should stick to your FileReader. I just use Scanner because I find input redirection easy to work with. You should be able to pull all of the `database.txt` file input from your code to make this work.

    3. COThanks a lot. I've managed to implement the code and it's working great. Marking your answer as THE answer. Thanks again @SaviorSelf :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
