<DL>
<DD>Constructs a new map with initial capacity, and load factor.
<p/>
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.
