1.EnumSet:EnumSet 是一个专门的实现放接口用于枚举类型。它扩展了 AbstractSet 并实现了 Java 中的 Set 接口。 EnumSet的几个要点如下: EnumSet 类是Java Collections Framework的成员,并且它不同步。 EnumSet 中的所有元素必须来自显式或隐式创建集合时指定的单个enumeration type。 EnumSet 比HashSet快得多。 EnumS...
How many ways to iterate a TreeSet in Java - A Treeset is a subclass of AbstractSet class and implements NavigableSet Interface. By Default, a Treeset gives an ascending order of output and it will use a Comparable interface for sorting the set elements.
Set− It is the sub interface of java Collection Interface that doesn’t allow duplicate values. It is similar to mathematical set. TreeMap 的翻译为: 树图 It is a class that is used to implement NavigableMap Interface. It stores the elements of the map in a tree structure. It provides ...
For those who are new to TreeSet, A TreeSet is a sorted collection in Java. You insert an element in any order but when you iterate through the collection, the values are automatically presented in the sorted order. The sorting is accomplished by a tree data structure. The current implem...
TreeSet is sorted collection class Sorting of objects in TreeSet in natural order by default or we can provide comparator class reference for customized sorting. While working with large amount of data access and retrieval is faster with TreeSet...

sb.append("\n");intmaxConfLength = maxLength(configurationNames);// We're sorting the names of the configurations and later attributes// to make sure the output is consistently the same between invocationsfor(finalString config : configurationNames) { ...
As the name of the classsuggests, the sorting is accomplished by a tree data structure(The current implementation uses a red-black tree). Every time an element is added to a tree, it is placed into its proper sorting position. Therefore, the iterator always visits the elements in sorted or...
