I tried to format a long number with underscore, but the number didn’t get formatted with commas. I am using sdk 16 ,intelliJ as my editor and windows OS.
Please show your code and your output, then it will be easier for someone to help.

Updating with screen print of the code…
You can use the underscore to format constant values in your code for readability. It’s a substitute because you can’t use a comma since that is already used as a separator in Java.
To format values in your program output you can use String.format() or NumberFormat which are covered later in the course.
