FiltersDefinition
```
public class ArrayList
extends Object
implements List, Serializable
```
The LEAP (environment-dependent) version of the &qote;java.util.ArrayList&qote; class. This class appears to be exactly the same in J2SE, PJAVA and MIDP. The internal implementation is different in the three cases however.
