value
- new value to be stored in this entry
public boolean equals(Object o)
true
if the given object is also a map entry and
the two entries represent the same mapping. More formally, two
entries e1
and e2
represent the same mapping
if(e1.getKey()==null ? e2.getKey()==null : e1.getKey().equals(e2.getKey())) && (e1.getValue()==null ? e2.getValue()==null : e1.getValue().equals(e2.getValue()))This ensures that the
equals
method works properly across
different implementations of the Map.Entry
interface.
o
- object to be compared for equality with this map entry
true
if the specified object is equal to this map
entryhashCode()
public int hashCode()
e
is defined to be: (e.getKey()==null ? 0 : e.getKey().hashCode()) ^ (e.getValue()==null ? 0 : e.getValue().hashCode())This ensures that
e1.equals(e2)
implies that
e1.hashCode()==e2.hashCode()
for any two Entries
e1
and e2
, as required by the general
contract of Object.hashCode()
.
