如何将格式设置为JFormattedTextField

Question

I want to use a JFormattedTextField that can input fraction numbers. As Java doc specifies its format should set within the constructor. But I'm using NetBeans IDE, the constructor of the JFormattedTextField is a generated code , so I don't know how to specify a format.

And if you can please direct me to a helpful tutorial.

To customize the creation code of a Swing element in NetBeans, right-click the element and select Customize code... . In the following pop-up, click the drop-down menu next to the code snippet and select Custom creation . Then you can specify the code yourself as such:

DecimalFormat df = DecimalFormat.getInstance();
// do some manipulation to the DecimalFormat object if desired
jFormattedTextField = new javax.swing.JFormattedTextField(df);
