Creates an entry representing a mapping from the specified key to the specified value.

key	the key represented by this entry
value	the value represented by this entry

Creates an entry representing the same mapping as the specified entry.

entry

the entry to copy

Compares the specified object with this entry for equality. Returns 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
return	true if the specified object is equal to this map entry

Returns the hash code value for this map entry. The hash code of a map entry 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.

return	the hash code value for this map entry
See also	equals

Returns a String representation of this map entry. This implementation returns the string representation of this entry's key followed by the equals character ("=") followed by the string representation of this entry's value.

return

a String representation of this map entry

Returns the key corresponding to this entry.

return

the key corresponding to this entry

Replaces the value corresponding to this entry with the specified value (optional operation). This implementation simply throws UnsupportedOperationException, as this class implements an immutable map entry.

value	new value to be stored in this entry
return	(Does not return)
Throws	UnsupportedOperationException: always

Returns the value corresponding to this entry.

return

the value corresponding to this entry
