Replacement operation has no effect
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.
