[HD-OCP17/21-Fundamentals Pg 0, Sec. 2.3.3 - literals]

[joaoclopes]

Hello, just wanted to add here:

To make it easy to read and comprehend large numbers, Java allows underscores in numeric literals. For example, 1000000.0 can also be written as 1_000_000.0. You cannot start or end a literal with an underscore. You can use multiple underscores consecutively. You need not worry about the rules governing the usage of underscores in hexadecimal, binary, and octal number formats.

You can't also use underscores before or after the dot "." on the double or float literal.

Thanks for the amazing book!
