    <p>My favorite way to read a small file is to use a BufferedReader and a StringBuilder. It is very simple and to the point (though not particularly effective, but good enough for most cases):</p> <pre><code>BufferedReader br = new BufferedReader(new FileReader("file.txt")); try { StringBuilder sb = new StringBuilder(); String line = br.readLine(); while (line != null) { sb.append(line); sb.append(System.lineSeparator()); line = br.readLine(); } String everything = sb.toString(); } finally { br.close(); } </code></pre> <p>Some has pointed out that after Java 7 you should use <a href="https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html">try-with-resources</a> (i.e. auto close) features:</p> <pre><code>try(BufferedReader br = new BufferedReader(new FileReader("file.txt"))) { StringBuilder sb = new StringBuilder(); String line = br.readLine(); while (line != null) { sb.append(line); sb.append(System.lineSeparator()); line = br.readLine(); } String everything = sb.toString(); } </code></pre> <p>When I read strings like this, I usually want to do some string handling per line anyways, so then I go for this implementation.</p> <p>Though if I want to actually just read a file into a String, I always use Apache <a href="http://commons.apache.org/proper/commons-io/">Commons IO</a> with the class IOUtils.toString() method. You can have a look at the source here:</p> <p><a href="http://www.docjar.com/html/api/org/apache/commons/io/IOUtils.java.html">http://www.docjar.com/html/api/org/apache/commons/io/IOUtils.java.html</a></p> <pre><code>FileInputStream inputStream = new FileInputStream("foo.txt"); try { String everything = IOUtils.toString(inputStream); } finally { inputStream.close(); } </code></pre> <p>And even simpler with Java 7:</p> <pre><code>try(FileInputStream inputStream = new FileInputStream("foo.txt")) { String everything = IOUtils.toString(inputStream); // do something with everything string } </code></pre>

    1. COI've made a small adjustment to stop adding a newline ( \n ) if the last line is reached. `code` while (line != null) { sb.append(line); line = br.readLine(); // Only add new line when curline is NOT the last line.. if(line != null) { sb.append("\n"); } }`code`

    2. COI feel it is better to explicitly give the encoding option and use the FileInputStream rather than directly the FileReader ? See this question too http://stackoverflow.com/questions/696626/java-filereader-encoding-issue `reader = new InputStreamReader(new FileInputStream("<filePath>", "UTF-8");

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.
