toMerge
- The Map
to merge with this one.NullPointerException
- if toMerge map is null or if some key in the map is null.IllegalArgumentException

true
if this map contains a mapping for the specified key. More formally, returns true
if and only if this map contains a mapping for a key k
such that (key==null ? k==null : key.equals(k))
. (There can be at most one such mapping.)containsKey

key
- key whose presence in this map is to be tested.true
if this map contains a mapping for the specified key.NullPointerException
- if key is nullClassCastException
- if key is not StringIllegalArgumentException
- if key is empty StringObject get(Object key)
null
if the map contains no mapping for this key. 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. 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.)

k
to value v
such that (key==null ? k==null : key.equals(k))
, that mapping is removed. (The map can contain at most one such mapping.) Returns the value to which the map previously associated the key, or null
if the map contained no mapping for this key. (A null
return can also indicate that the map previously associated null
with the specified key if the implementation supports null
values.) The map will not contain a mapping for the specified key once the call returns.

- key whose mapping is to be removed from the map.null
