    <p>From the code you posted, you're not trying to "copy" the stream, but read it into a string.</p> <p>You can simply provide the encoding in <a href="http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#String%28byte%5B%5D,%20int,%20int,%20java.lang.String%29" rel="nofollow">the <code>String</code> constructor</a>:</p> <pre><code>s = new String(bytes, "ISO-88591-1"); </code></pre> <p>Personally I'd just replace the whole method with a call to the <a href="https://code.google.com/p/guava-libraries/" rel="nofollow">Guava</a> <a href="http://docs.guava-libraries.googlecode.com/git-history/release/javadoc/com/google/common/io/Files.html#toString%28java.io.File,%20java.nio.charset.Charset%29" rel="nofollow">method <code>Files.toString()</code></a>:</p> <pre><code>String content = Files.toString(new File(filename), StandardCharsets.ISO_8859_1); </code></pre> <p>If you're using Java 6 or earlier, you'll need to use the Guava field <a href="http://docs.guava-libraries.googlecode.com/git-history/release/javadoc/com/google/common/base/Charsets.html#ISO_8859_1" rel="nofollow">Charsets.ISO_8859_1</a> instead of <a href="http://docs.oracle.com/javase/7/docs/api/java/nio/charset/StandardCharsets.html#ISO_8859_1" rel="nofollow"><code>StandardCharsets.ISO_8859_1</code></a> (which was only introduced in Java 7).</p> <p><em>However</em> your use of the term "copy" suggests that you want to write the result to some other file (or stream). <em>If that is true</em>, then you don't need to care about the encoding at all, since you can just handle the <code>byte[]</code> directly and avoid the (unnecessary) conversion to and from <code>String</code>.</p>

    1. COinteresting. Ive never used the Guava libraries. is it notable faster than the standard java.io.* libraries?

    2. CO@recursive9: no, it's probably not noticable faster, but I assume it will be among the fastest ways you can do that task. To be honest: **how** you use an API probably has a lot more impact on performance (when it comes to I/O) than *which* API you use. For example in your first code above you read the file line-for-line for no apparent reason. This means that a.) there will be more method calls and b.) that you add the task of finding line separators and creating separate `String` objects for each line. Try to modified the code above to simply read as much characters as possible each time ...

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.
