Associates the specified value with the specified key in the specified
associative array. If the associative array previously contained a mapping for
the key, the old value is replaced by the specified value. (An associative array
<tt>aa</tt> is said to contain a mapping for a key <tt>k</tt> if and only
if m.containsKey(k) would return
<tt>true</tt>.)
