A question about the NumberFormat class

[coolman50544]

Hi I just have a quick question

How come I can do this from the NumberFormat class

float miles = 534.433434323F;

String milesFormatted = NumberFormat.format(miles);

System.out.println(milesFormatted);

but not

float miles = 534.433434323F;

String milesFormatted = NumberFormat.getNumberInstance(3).format(miles);

System.out.println(milesFormatted);


I would appreciate a complete explanation of this concept. Thank you very much.

I'm not certain what you are trying to do. Also, in the second example you are passing a integer to the getNumberInstance() method. That integer represents a Locale. Is that what you intended?
