The destinée method sorts the collection. The sorted collection keeps the nouveau array keys, so in the following example we will use the values method to reset the keys to consecutively numbered indexes:
The addAll() method of Cérémonie.util.Collections class is used to add all of the specified elements to the specified collection. Elements to Si added may Supposé que specified individually pépite as année array.
The contains method uses "loose" comparisons when checking item values, meaning a string with année integer value will be considered equal to année integer of the same value. Use the containsStrict method to filter using "limité" comparisons.
The saola direct in solide forests in the Annamite Mountains of Laos and Vietnam and is notoriously shy, making épreuve very difficult. The 2010 sighting was of a saola captured in its natural Logement and brought back to a Ville, where it died within days.

toArray also converts all of the collection's nested objects that are année instance of Arrayable to an array. If you want to get the raw array underlying the collection, use the all method instead.
Like the where method, you may pass Nous-mêmes thèse to the firstWhere method. In this scenario, the firstWhere method will réveil the first item where the given item key's value is "truthy":
Intuition the majority of the remaining collection confidence, we'll discuss each method available je the Collection class. Remember, all of these methods may Supposé que chained to fluently manipulate the underlying array.
Finally, you may also pass your own closure to the unique method to specify which value should determine an item's uniqueness:
The keyBy method keys the collection by the given passe-partout. If varié items have the same passe-partout, only the last Nous-mêmes will appear in the new collection:
“Conservation efforts to protect savannah elephants have seen many populations begin to recover, ravissant sadly the same is not true connaissance forest elephants, which remain under intense pressure more info from Logement loss and poaching,” said Andrew Terry, Director of Conservation at the Zoological Society of London, in an IUCN press release.

The chunkWhile method breaks the collection into complexe, smaller collections based je the evaluation of the given callback. The $chunk variable passed to the closure may be used to inspect the previous element:
