Performs the given action on each entry in this map until all entries have been processed or the action throws an Exception. Exceptions thrown by the action are relayed to the caller. The entries will be processed in the same order as the entry set iterator unless that order is unspecified in which case implementations may use an order which differs from the entry set iterator.

Parameters:

     // Work with cur.key() and cur.value()
     // Call cur.remove() to remove the current entry
 }

Returns:

a new cursor over the entries of this map

Returns:

the previous value associated with key, or default value if there was no mapping for key. (A default value return can also indicate that the map previously associated default value with key.)

Parameters:

key - key with which the specified value is to be associated

value - value to be associated with the specified key
