In short, what you need is a fast set. So far we have learned what are differences between java.util.HashSet, java.util.LinkedHashSet and java.util.TreeSet in java. The Set adds a strong contract on the behavior of hashCode and equals operations. LinkedHashSet Class in Java with Example - BeginnersBook LinkedHashSet(int size): Initializes with a capacity.
