Question

I am using Java Util logging and whenever I do statement like this

logger.log(Level.INFO, "print this number = {0}", number);

it formats my number from 278487683165614 to 278,487,683,165,614

this is extremely annoying while searching through logs.

Can i stop it from doing this ? Please help.

Try one of the below (don’t have the visibility of your number object type):

1. Using String.valueOf()

   logger.log(Level.INFO, "print this number = {0}", String.valueOf(number));
   

2. Using Number.toString

   logger.log(Level.INFO, "print this number = {0}", number.toString);
   

3. Using NumberFormat.setGroupingUsed(false)

   NumberFormat formatter = new NumberFormat();     
   formatter.setGroupingUsed(false);
   logger.log(Level.INFO, "print this number = {0}", formatter.format(number));
