question: public static ArrayList < Object > deleteItemSets ( ArrayList < Object > itemSets , int minSupport , int maxSupport ) { ArrayList < Object > newVector = new ArrayList < Object > ( itemSets . size ( ) ) ; for ( int i = 0 ; i < itemSets . size ( ) ; i ++ ) { ItemSet current = ( ItemSet ) itemSets . get ( i ) ; if ( ( current . m_counter >= minSupport ) && ( current . m_counter <= maxSupport ) ) { newVector . add ( current ) ; } } return newVector ; }
target:  Deletes all item sets that don't have minimum support.
