方法名：doubleCapacity

Hashtable.doubleCapacity介绍

[英]Doubles the capacity of the hash table. Existing entries are placed in the correct bucket on the enlarged table. If the current capacity is, MAXIMUM_CAPACITY, this method is a no-op. Returns the table, which will be new unless we were already at MAXIMUM_CAPACITY.
[中]使哈希表的容量加倍。现有条目放在放大表上的正确桶中。如果当前容量为最大容量，则此方法为不可操作。返回表，除非我们已经达到最大容量，否则该表将是新的。
