Hashset Java Example - Examples Java Code Geeks - 2024

WebFor example, the product of capacity and loadfactor is 101*0.5=50.5. It means that after storing 50th element into the HashSet; its capacity will be internally increased to store more elements. The initial default capacity of HashSet is 16. The default load factor is 0.75. HashSet Implementation WebHashSet hs = new HashSet (Collection collection); Example Let's consider a HashSet created with an initial capacity of 20 and a load factor of 0.75. Keeping the load factor as 0.75 implies the size of the internal HashMap will be increased for the first time when it has 15 (75% of 20) elements in it. WebCreates an empty HashSet. The hash set is initially created with a capacity of 0, so it will not allocate until it is first inserted into.
