Interface Map.Entry<K,V>

All Known Implementing Classes:
AbstractMap.SimpleEntry, AbstractMap.SimpleImmutableEntry
Enclosing interface:
Map<K,V>
public static interface Map.Entry<K,V>
Map.Entry is a key/value mapping contained in a Map.

  • Method Details

    • equals

      boolean equals(Object object)

      Compares the specified object to this Map.Entry and returns if they are equal. To be equal, the object must be an instance of Map.Entry and have the same key and value.

      Parameters
      • object: the Object to compare with this Object.
      Returns
      Overrides:
      equals in class Object
      Returns:

      true if the specified Object is equal to this Map.Entry, false otherwise.

      • #hashCode()

    • getKey

      K getKey()

      Returns the key.

      Returns

      the key

    • getValue

      V getValue()

      Returns the value.

      Returns

      the value

    • hashCode

      int hashCode()

      Returns an integer hash code for the receiver. Object which are equal return the same value for this method.

      Returns

      the receiver's hash code.

      See also
      • #equals(Object)
      Overrides:
      hashCode in class Object

    • setValue

      V setValue(V object)

      Sets the value of this entry to the specified value, replacing any existing value.

      Parameters
      • object: the new value to set.
      Returns

      object the replaced value of this entry.

    • comparingByKey

      static <K extends Comparable<? super K>, V> Comparator<Map.Entry<K,V>> comparingByKey()
      Orders entries by the natural order of their keys.

    • comparingByValue

      static <K, V extends Comparable<? super V>> Comparator<Map.Entry<K,V>> comparingByValue()
      Orders entries by the natural order of their values.

    • comparingByKey

      static <K,V> Comparator<Map.Entry<K,V>> comparingByKey(Comparator<? super K> comparator)
      Orders entries by their keys, as comparator orders them.

    • comparingByValue

      static <K,V> Comparator<Map.Entry<K,V>> comparingByValue(Comparator<? super V> comparator)
      Orders entries by their values, as comparator orders them.
