Returns the value to which the specified key is mapped in this identity
hash map, or <tt>null</tt> if the map contains no mapping for this key.
A return value of <tt>null</tt> does not <i>necessarily</i> indicate
that the map contains no mapping for the key; it is also possible that
the map explicitly maps the key to <tt>null</tt>. The
<tt>containsKey</tt> method may be used to distinguish these two cases.

@param   key the key whose associated value is to be returned.
@return  the value to which this map maps the specified key, or
<tt>null</tt> if the map contains no mapping for this key.
@see #put(Object, Object)
Returns the value to which the specified key is mapped in this identity hash map or <tt > null< / tt > if the map contains no mapping for this key . A return value of <tt > null< / tt > does not <i > necessarily< / i > indicate that the map contains no mapping for the key ; it is also possible that the map explicitly maps the key to <tt > null< / tt > . The <tt > containsKey< / tt > method may be used to distinguish these two cases .
