Unnecessary boxing
Reports explicit boxing, that is wrapping of primitive values in objects.
Explicit manual boxing is unnecessary as of Java 5 and later, and can safely be removed.
Examples:
Integer i = new Integer(1);
→Integer i = Integer.valueOf(1);
int i = Integer.valueOf(1);
→int i = 1;
- 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.
UnnecessaryBoxing
Use the Only report truly superfluously boxed expressions option to report only truly superfluous boxing, where a boxed value is immediately unboxed either implicitly or explicitly. In this case, the entire boxing-unboxing step can be removed. The inspection doesn't report simple explicit boxing.
This inspection only reports if the language level of the project or module is 5 or higher.
Here you can find the description of settings available for the Unnecessary boxing inspection, and the reference of their default values.
