The java.text.MessageFormat code format lets you use strings that are constructed dynamically at runtime. The dynamically added elements are stored in an array of objects, which is passed as a parameter to java.text.MessageFormat. You can use the Message Format Arguments dialog box to specify the values of these objects.
You can add arguments when you use the org.openide.util.NbBundle.getMessage format. This format is part of the NetBeansTM APIs and is used to build modules for the IDE. Consult the NetBeans API documentation for more information on this format.
To enter substitution parameters for a message format:
A series of parameters, beginning with 0, is added to the text field.
The arguments you supply are substituted for the {arguments} wild card in the following format:
java.text.MessageFormat(java.util.ResourceBundle.getBundle("bundle name").getString("key"), new Object[] {arg1, arg2, arg3})
