All Implemented Interfaces:

Detector, Priorities, StatelessDetector, java.lang.Cloneable, org.apache.bcel.classfile.Visitor
```
public class InefficientToArray
extends BytecodeScanningDetector
implements StatelessDetector
```
Find occurrences of collection.toArray( new Foo[0] ); This causes another memory allocation through reflection Much better to do collection.toArray( new Foo[collection.size()] );
