Answer 1

Underscores were introduced in Java to enhance readability of large numbers and it is completely legal to use. There is no difference between them. The compiler just ignores the underscore.

Answer 2

Numeric literals in Java can contain underscore, as long as it is not directly next to the decimal separator.
This feature is supposed to make it easier to write / read long numbers, like you can write two millions as 2_000_000 instead of 2000000
Easier to read right?
