public IntHashMap(int capacity)
capacity
- the initial capacity.public IntHashMap(int capacity, double factor)
The capacity is the number of keys that can be mapped without resizing the arrays in which keys and values are stored. For efficiency, only a fraction of the elements in those arrays are used. That fraction is the specified load factor. The initial length of the arrays equals the smallest power of two not less than the ratio capacity/factor. The capacity of the map is increased, as necessary. The maximum number of keys that can be mapped is 2^30.
