NumberFormat text field without commas

Question

I have a JFormattedTextField which I want to accept numbers in the 5 digit range. The following code works correctly:

myNumberBox = new JFormattedTextField(N         


        

Answer 1

You have to disable the grouping in your NumberFormat object like this:

NumberFormat format = NumberFormat.getIntegerInstance();
format.setGroupingUsed(false);
myNumberBox = new JFormattedTextField(format);

See: NumberFormat.setGroupingUsed
