2. Create anArrayList ArrayListhas several constructors and we will present them all in this section. First, notice thatArrayListis a generic class, so you can parameterize it with any type you want and the compiler will ensure that, for example, you will not be able to putIntegervalues in...
making it great for beginners. However, it does have a potential pitfall: it creates an empty ArrayList. If you need an ArrayList with predefined elements, you’ll need to add them manually using theaddmethod or use a different method of initialization, which we’ll cover in the next section...

所以在 ArrayList LinkedList 类中我们可以看到它们都重写了 set(int index, E element)、add(E element)、remove(int index)…… 等方法用于修改当前列表的内容。我们将在后面的篇幅详细讨论这两种数据结构。 我们还注意到:在类的 iterator() 和listIterator(final int index) 方法中分别返回了一个 Itr 对象和...

From 8u20 release onwards Collection.sort defers to List.sort. This means, for example, existing code that calls Collection.sort with an instance of ArrayList will now use the optimal sort implemented by ArrayList.See 8032636.Area: core-libs/java.net...
