ArrayList.newCapacity介绍

[英]This method controls the growth of ArrayList capacities. It represents a time-space tradeoff: we don't want to grow lists too frequently (which wastes time and fragments storage), but we don't want to waste too much space in unused excess capacity. NOTE: This method is inlined into #add(Object) for performance. If you change the method, change it there too!
[中]此方法控制ArrayList的增长容量。它代表了一种时空权衡：我们不希望列表增长太频繁（这会浪费时间和存储碎片），但我们不希望在未使用的过剩容量中浪费太多空间。注意：为了提高性能，此方法内联到#add（Object）中。如果你改变方法，也要在那里改变！
