question: public static < T , R > R [ ] map ( Collection2 < T > coll , Function < ? super T , ? extends R > evalFunction , Class < R > klass ) { R [ ] newArray = create ( coll . size ( ) , klass ) ; int i = 0 ; for ( T elem : coll ) { newArray [ i ] = evalFunction . apply ( elem ) ; i ++ ; } return newArray ; }
target:  Creates a new array, based on given coll, whose elements are produced element-wise from the original  coll using given evalFunction.
