Underscores in numeric literal

Reports numeric literals with underscores and suggests removing them with a quick-fix. This may be useful if you need to lower the language level.

The quick-fix removes underscores from numeric literals. For example 1_000_000 will be converted to 1000000.

Numeric literals with underscores appeared in Java 7. This inspection can help to downgrade for backward compatibility with earlier Java versions.

New in 2020.2
