    <p>I have a problem but I don't know how to solve it: I need to get a Long number from a String (I get this string in a SAXparser class I wrote to get some fields from an XML file).</p> <p>Here you are the problematic code:</p> <pre><code>if (bprice) { String price = new String(ch, start, length); System.out.println("Product price: " + price); bprice = false; if (price.equalsIgnoreCase("0")) product.price = null; else product.price = Long.parseLong(price); } </code></pre> <p>(<strong>product</strong> is an instance from an object where I store all the product information. I got the error in the last line)</p> <p>I debugged it and I got this:</p> <blockquote> <blockquote> <p>Exception occurred in target VM: For input string: "1.04" java.lang.NumberFormatException: For input string: "1.04" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48) at java.lang.Long.parseLong(Long.java:419) at java.lang.Long.parseLong(Long.java:468) at parsers.LectorXML.characters(LectorXML.java:325) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.characters(AbstractSAXParser.java:538) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:464) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:808) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:737) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:119) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1205) at parsers.LectorXML.leer(LectorXML.java:71) at parsers.LeerXML.main(LeerXML.java:20) &lt;</p> </blockquote> </blockquote>

    1. COWhat's your question? It's quite obvious that 1.04 is not a valid long number.

    2. COYou should not use `long` or floating point numbers to store prices, unless the prices are expressed in cents (104 instead of 1.04). The most precise type for storing monetary data is [`BigDecimal`](http://docs.oracle.com/javase/6/docs/api/java/math/BigDecimal.html)

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.
