  • Use of Javas Collections. singletonList()? - Stack Overflow
    Collections singletonList will create an immutable List An immutable List (also referred to as an unmodifiable List) cannot have it's contents changed The methods to add or remove items will throw exceptions if you try to alter the contents A singleton List contains only that item and cannot be altered
  • java - What is the use of singletonList? - Stack Overflow
    singletonList() is (thread-)safe (due to immutability), fast and compact [1] E g in scala there is a separete hierarchy for mutable and immutable collections and API can choose whether it accept this or the other (or both, as they have common base interfaces)
  • Arrays. asList () vs Collections. singletonList () - Stack Overflow
    Collections singletonList(something) is immutable whereas Arrays asList(something) is a fixed size List representation of an Array where the List and Array gets joined in the heap Arrays asList(something) allows non-structural changes made to it, which gets reflected to both the List and the conjoined array
  • java - Use Case : Collection. singletonList Vs Collection . . .
    singletonList takes an item, and creates an immutable list containing only that item unmodifiableList takes a list, and creates an immutable list that references that list It is analogous to the difference between add and addAll One takes an item, one takes a list containing items
  • Is there analog Collections. singleton () Collections. singletonList . . .
    I don't think that any of two points is convincing enough - ofc, we can construct a collection from another collection but it is always an unnecessary overhead; also there's nothing harmful - I want a List and I don't need to know its actual implementation - only the fact that it is a mutable one, e g if I pass it to Hibernate it internally may need to modify it (that's my case)
  • Should we add null to the list Collection. singletonlist or just make . . .
    I do have question about adding null to the list in my example I will use Collections singletonList(value) So lets say I do have somethin like this: String value = null; List<String> test = Collections singletonList(value); in this case I will get singleton list which, contains null So we do have List object which is wrapping single null value
  • Getting the object of a singleton collection - Stack Overflow
    I want to get the object of a collection that I know has exactly one element (basically it's the reverse of what Collections singletonList() does - but I don't know whether the collection is list set
  • Using List. of () for immutable list with single element instead of . . .
    Prefer using factory method List<String> immutableList1 = List of("one"); Because they disallow null elements is one of the benefit and also factory methods in List interface are handy to add multiple objects and creates immutable List
