19. (5 points) Circle TRUE or FALSE (Refer to the UMLs. Please answer the questions based upon the contents/codes we have discussed in class up to now.) TRUE / FALSE TRUE / FALSE The implementation (i.e., body) of ListArrayBased() is identical to that of remove Allo The implementation (i.e., body) of isEmpty in ListArrayBased class is identical to that of isEmpty in List ReferenceBased class. The implementation (i.e., body) of size() in ListArrayBased class is identical to that of size() in ListReferenceBased class. The implementation (i.e., body) of ListReferenceBased is identical to that of remove Allo TRUE / FALSE TRUE / FALSE Both ListArrayBased and ListReferenceBased classes implement ListInterface. TRUE / FALSE If needed, refer to the following UML diagrams. NOTE: (1) Array index starts from 0, not from 1 in UstArrayBlased, (2) Notice that a new method, getHead(), is defined in List ReferenceBased and you are asked to use it for some questions > Listinterface IsEmpty: Boolean size(): int add indexint, item: Object); void getfindexInt): Object remove(index Int): vold removeAll(): vold ListReferenceBased -head: Node -numitems in ListArrayBased -MAX_UST: Int -Items: Object -numitems in +ListArrayBased +Empty(): boolean sitel): int add indexint, Item: Object): void -petfindexinth: Object tremove(index int:void *removeAnc): vold +List Reference Based tisEmpty: boolean size:int add index int, item: Object vold petfindex: int: Object remove(index inti:void remove(): void getHead(): Node Sortedlist Array Rased SortedReference Based + Sorted ListArray Based + add itemt Object) void + remove item: Object) void + locatelndex ToAdd(item: Object locateIndex ToRemove(item: Object); int +Sorted List Reference Based + addiem: Object void remove(item Objectivoid locateIndex TsAddiem: Object in + locatendeToRemove itcm: Object Page 2 of 19
