I was looking around for the class to format a number to 2 decimal places while I was coding Java, or specifically JSP, and I found it.
First, you need to import the DecimalFormat class, so have this line at the top of your Java file:
Or if you’re running JSP:
<%@page import="java.text.DecimalFormat" %>
And here’s the actual code that does the magic:
double price = 10.59;
DecimalFormat priceFormatter = new DecimalFormat("$#0.00");
That’s all there is to it! Simply change the Formatting string “$#0.00” to anything you wish. The pound (#) sign simply means there can be optional digits there. The two zero’s (0) to the right of the decimal place means that it has only 2 decimal places, and will be replaced by 0s if you don’t have digits there. Te $ sign right at the start is something that I put in, because I wanted to display my prices in dollars ($).
So for example, you can also have the formatting string as “#0.00 seconds more” and it’ll show “2343.36 seconds more”.
