- All Implemented Interfaces:
- Configurable, Contextualizable
- public class RedundantImportCheck
- extends Check
Checks for imports that are redundant. An import statement is
considered redundant if:
- It is a duplicate of another import. This is, when a class is imported
more than once.
- The class imported is from the
java.lang
package.
For example importing java.lang.String
.
- The class imported is from the same package.
An example of how to configure the check is:
<module name="RedundantImport"/>
