- - ### Constructor Detail

    - #### Pair

          public Pair​(K key,
                      V value)

      Creates a new pair
      Parameters:
        `key` - The key for this pair
        `value` - The value to use for this pair

  - ### Method Detail

    - #### getKey

          public K getKey()

      Gets the key for this pair.
      Returns:
        key for this pair

    - #### getValue

          public V getValue()

      Gets the value for this pair.
      Returns:
        value for this pair

    - #### toString

          public String toString()

      `String` representation of this `Pair`.

      The default name/value delimiter '=' is always used.

      Overrides:
        `toString` in class `Object`
      Returns:
        `String` representation of this `Pair`

    - #### hashCode

          public int hashCode()

      Generate a hash code for this `Pair`.

      The hash code is calculated using both the name and the value of the `Pair`.

      Overrides:
        `hashCode` in class `Object`
      Returns:
        hash code for this `Pair`

    - #### equals

          public boolean equals​(Object o)

      Test this `Pair` for equality with another `Object`.

      If the `Object` to be tested is not a `Pair` or is `null`, then this method returns `false`.

      Two `Pair`s are considered equal if and only if both the names and values are equal.

      Overrides:
        `equals` in class `Object`
      Parameters:
        `o` - the `Object` to test for equality with this `Pair`
      Returns:
        `true` if the given `Object` is equal to this `Pair` else `false`
