How can I output only a certain number of digits after a decimal place in a JTextComponent?

I am using both JLabels and JTextFields, and need to be able to truncate my doubles to two decimal places when they are displayed by the application.

How can开发者_如何学C I perform this truncation, preferably without switching to JFormattedTextFields?

You can use DecimalFormat class. Here is an explanation

Prefer the Swing JFormattedTextField instead; see the Java Tutorial.
