Java
Replacement operation has no effect
Warning
New
Last modified: 03 December 2024 Reports calls to the String
methods replace()
, replaceAll()
or replaceFirst()
that have no effect. Such calls can be guaranteed to have no effect when the qualifier and search string are compile-time constants and the search string is not found in the qualifier. This is redundant and may indicate an error.
Example:
// replacement does nothing
"hello".replace("$value$", value);
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
