Unnecessary unboxing
Reports unboxing, that is explicit unwrapping of wrapped primitive values.
Unboxing is unnecessary as of Java 5 and later, and can safely be removed.
Examples:
Integer i = Integer.valueOf(42).intValue();→Integer i = Integer.valueOf(42);int k = Integer.valueOf(42).intValue();→int k = Integer.valueOf(42);(reports only when the Only report truly superfluously unboxed expressions option is not checked)
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.
UnnecessaryUnboxing- 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 unboxed expressions option to only report truly superfluous unboxing, where an unboxed value is immediately boxed either implicitly or explicitly. In this case, the entire unboxing-boxing step can be removed. The inspection doesn't report simple explicit unboxing.
This inspection only reports if the language level of the project or module is 5 or higher.
