我收到以下編譯錯(cuò)誤：javac -cp "/Users/myname/Desktop/Projects/Project/target/jarname.jar" Util.java -Xlint:uncheckedUtil.java:51: error: incompatible types: inference variable R has incompatible bounds            tags = Arrays.stream(tagArray).collect(Collectors.toList());                                                  ^    equality constraints: List<String>    upper bounds: ArrayList<String>,Object  where R,A,T are type-variables:    R extends Object declared in method <R,A>collect(Collector<? super T,A,R>)    A extends Object declared in method <R,A>collect(Collector<? super T,A,R>)    T extends Object declared in interface Stream1 error現(xiàn)在我的印象是，您應(yīng)該能夠通過這種方式將所有 Stream 元素放入一個(gè)列表中。我對(duì) Java 有點(diǎn)陌生......我在這里不明白什么？這是在 Util.java 中導(dǎo)致問題的函數(shù)：public static GoogleMerchantDetailsDto convertGoogleMerchantDetails(SqlRow row) {    Array rawTagArray = (Array) row.get("tags");    ArrayList<String> tags = new ArrayList();    if (rawTagArray != null) {        String[] tagArray = Util.toStringArray(rawTagArray);        tags = Arrays.stream(tagArray).collect(Collectors.toList());    }    String distanceFrom = String.format("%,.1f", row.getDouble("distance_from"));    String latitude = String.format("%,.6f", row.getDouble("latitude"));    String longitude = String.format("%,.6f", row.getDouble("longitude"));    GoogleMerchantDetailsDto googleMerchant = GoogleMerchantDetailsDto.builder().withId(row.getString("id"))            .withName(row.getString("name")).withTags(tags).withDistanceFrom(distanceFrom).withLatitude(latitude)            .withLongitude(longitude).withIsFavorite(row.getBoolean("is_favorite"))            .withWaitlist(row.getInteger("waitlist")).withAddress1(row.getString("vicinity")).build();    return googleMerchant;}
