Java
Too weak variable type leads to unnecessary cast
Warning
New
Last modified: 03 December 2024Reports type casts that can be removed if the variable type is narrowed to the cast type.
Example:
Object x = " string ";
System.out.println(((String)x).trim());
Here, changing the type of x
to String
makes the cast redundant. The suggested quick-fix updates the variable type and removes all redundant casts on that variable:
String x = " string ";
System.out.println(x.trim());
- 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.
