Method Detail

put

public Object put(Object key,
                  Object value)

Associates a given value with a given key. Removes the previous associated value, if there is any.

Specified by:

put in interface Map<Object,Object>

Overrides:

put in class Hashtable<Object,Object>

Parameters:

key - The key for the given value

value - The value for the given key

Returns:

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