<p>
A <i>numeric type</i> represents sets of integer or floating-point values.
The predeclared architecture-independent numeric types are:

<pre class="grammar">
uint8       the set of all unsigned  8-bit integers (0 to 255)

   * numbers of keys and values without resizing.
   *
   * <p>This method will soon be deprecated in favor of {@code
   * MultimapBuilder.hashKeys(expectedKeys).arrayListValues(expectedValuesPerKey).build()}.
   *
   * @param expectedKeys the expected number of distinct keys
   * @param expectedValuesPerKey the expected average number of values per key

Pero como te alejas del mostrador y te sientas en la mesa con un número para tu turno, puedes cambiar tu atención 🔀 a esa persona 😍 y "trabajar" ⏯ 🤓 en eso. Entonces nuevamente estás haciendo algo muy "productivo" 🤓, como coquetear con esa persona 😍.
