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;
Locating this inspection
- 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- Via Settings dialog
Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
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.
