也就是说HashMap里面的数组的长度，始终都是2的n次幂。为了实现这个效果，它的扩容因子很自然就是2倍了。当然，把扩容因子设置成4倍、8倍、16倍等等也是一样可以实现的。或者假如不想要这个优化，就想自己搞一个按照 1.5 倍速度扩容的HashMap的话，完全重写一个HashMap也是OK的，这个只是为了性能优化，而不是一定

Java去掉了指针类型,并不表示程序设计师在开发高级数据结构Q,像堆栈(stack)、 队列(queue)、二元树(binarytree)时, 都必须要像在传统Basic上,利用大范围的数组来自行模拟系统内存,自行建构类似指针的表示方式。 相反地,Java提供 了和Lisp语言中相似的Reference类型,通过Reference去读取配置到的内存内容,可以确保不会去...
