If I use a HashSet with a initial capacity of 10 and a load fact开发者_运维技巧or of 0.5 then every 5 elements added the HashSet will be increased or first the HashSet
I need an example on how to use a comparable class on a 开发者_StackOverflowHashSet to get an ascending order. Let’s say I have a HashSet like this one:
This will probably be an extremely simple question. I\'m simply trying to remove duplicate byte[]s from a collection.
I have a program which fetches records from database (using Hibernate) and fills them in a Vector. There was an issue regarding the performance of the operation and I did a test with the Vector replac
Please, 开发者_开发知识库suggest the shortest way to convert Dictionary<Key, Value> to Hashset<Value>
Okay, often I\'ll have a method that returns a Set of some sort.The problem with unit testing such a method is that there is no guarantee an iteration over the set wi开发者_如何学JAVAll always return
Disclaimer: I realize the totally obvious answer to this question is HashSet<string>. It is absurdly fast, it is unordered, and its values are unique.
Running this code: public class SomeSet { public static void main(String[] args) { Set<Short> s = new HashSet<Short>();
I have a problem with hashsets at the moment. I have classes which are immutable and contain just one item, when I add two different classes with the same data to a hashset, I get them both in the set
If every object added to a java.util.HashSet implements Object.equals() and Object.hashCode() in a deterministic fashion, is the iteration order over the HashSet guaranteed to be identical for every i
