Formatting a value

[Mezan Shareef]

I have this code, There is object of type hashmap (h). I am working on JSP page. there are two values h.get ("drUnitCost") and h.get ("shippingFee") as 5.2345, and 0.3456 respectively. What i want is $5.23 and $0.34 for h.get ("drUnitCost") and h.get ("shippingFee") respectively.

unit cost and shipping fee these are the colums in my page and other few coumns like order details, order id, product code etc.

                        <html:hidden property="<%="orderDetailId["+i+"]"%>" value="<%=h.get("orderdetailid")+""%>"/>
			<td align="left"><font size="2px"><%=h.get("orderdetailid")+""%></font></td>
			<td align="center"><font size="2px"><%=h.get("productcode")+""%></font></td>
			<td align="center"><font size="2px"><%=h.get("name")+""%></font></td>
			<td align="center"><font size="2px"><%=h.get("quantity")+""%></font></td>
			<td align="center"><font size="2px"><%=h.get("status")+""%></font></td>
			<%if(userBean.isShowUnitCost()){ %>

java.util.Formatter, also available through String.format
java.text.DecimalFormat

Take your pick.

Actually, since it's a JSP we're discussing here, the relevant things to learn would be the JSTL or EL constructs for formatting numbers. Using Java constructs just reinforces the bad habit of including Java code in a JSP.

If it's a JSP, it would sit better on that forum. Moving.

Rule #1 of JSP: no Java code!

To format numbers, use the JSTL's <fmt:formatNumber> tag.

Thank you guys. I did it. I used java. To configure JSTL again it was like pain, so i did with java, very soon i will do with JSTL later.

Do it now. The longer you continue with bad habits, the harder they are to break.
