How do I format my percent variable to 2 decimal places?

Question

This program is basically working with text files, reading the data & performing functions:

while(s.hasNext()){
    name= s.next();

    mark= s.nextDouble()         


        

Answer 1

It may be best to acquire your percent formatter through NumberFormat.getInstance(Locale locale) and using the setMinimumFractionDigits methods (and maybe the others).
