All Implemented Interfaces:

Configurable, Contextualizable

public class NumericalPrefixesInfixesSuffixesCharacterCaseCheck
extends AbstractCheck

Checks that all numerical literal prefixes, infixes, and suffixes are written using lowercase letters (for example prefixes : 0x, 0b, infixes : e, p, suffixes : f, d). This convention follows the OpenJDK Style Guide.

ATTENTION:

This check ignores the L suffix for long literals, as using an uppercase L is a widely accepted and recommended practice to avoid confusion with the digit 1.

Since:

13.2.0
