public Object get(Object obj)

Overrides java.util.HashMap.get.

Implements java.util.Map.get.

Doc from java.util.HashMap.get.

Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

More formally, if this map contains a mapping from a key k to a value v such that (key==null ? k==null : key.equals(k)), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)

A return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.

Parameters
obj:Object

Doc from java.util.Map.get.

the key whose associated value is to be returned

Returns:Object

Doc from java.util.Map.get.

the value to which the specified key is mapped, or null if this map contains no mapping for the key

public Object put(Object key, Object value)

Overrides java.util.HashMap.put.

Implements java.util.Map.put.

Doc from java.util.HashMap.put.

Associates the specified value with the specified key in this map. If the map previously contained a mapping for the key, the old value is replaced.

Parameters
key:Object

key with which the specified value is to be associated

value:Object

value to be associated with the specified key

Returns:Object

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.)
