Otra buena alternativa es utilizar elSplitterclass de la biblioteca Guava para dividir la string, como se muestra a continuación. Esto devuelve unIterableen lugar de una array, que podemos pasar aLists.newArrayList(). Crea un mutableArrayListinstancia que contiene todos los elementos de laIterabl...
final List<Object> list = new ArrayList<>(); for (Object element : iterable) { list.add(converter.convert(targetComponentType, element)); // 可循环对象转数组,可循环对象无法获取长度,因此先转为List后转为数组 final List<?> list = IterUtil.toList((Iterable<?>) value); result = Array.newI...
The Applanga SDK will automatically initialize as soon as the first activity starts. This overcomes a lot of issues we had in the past regarding wrong initialization especially connected to deep link scenarios. You still can manually initialize Applanga, this is only needed if you want to use ...
In this quick tutorial, we’ll explore how to convert between List and Set in Kotlin. 2. Introduction to the Problem The problem looks pretty straightforward. We know both List and Set are subtypes of the Collection interface. Further, the Iterable interface is the supertype of the Collection...
For the same sampleListofString,we’ll now exploreflatMapIterable— a custom-built operator. Here, we don’t need to createFluxexplicitly from theList; we only need to provide theList. This operator implicitly creates aFluxout of its elements. Let’s useflatMapIterablefor our solution: ...

toList()); System.out.println(tokens); } } 下载 运行代码 输出: [a, b, c, d] 2.使用Guava 另一种选择是使用 Guava 的 Splitter 类来拆分字符串。它返回一个 Iterable 而不是可以传递给 Lists.newArrayList() 方法,导致 ArrayList 包含所有元素 Iterable. 1 2 3 4 5 6 7 8 9 10 11 12 13...
另一個不錯的選擇是使用Splitter來自 Guava 庫的類來拆分字符串,如下所示。這會返回一個Iterable而不是一個數組,我們可以傳遞給Lists.newArrayList().它創建了一個可變的ArrayList包含所有元素的實例Iterable.如果我們稍後需要添加或刪除元素,或者某些元素可以為空,則首選此方法。
