LinkedHashSet doesn’t have it’s own methods. All methods are inherited from it’s super class i.e HashSet. So. all operations on LinkedHashSet work in the same manner as that of HashSet. The only change is the internal object used to store the elements. In hashSet, elements you i...
LinkedHashSet is between HashSet and TreeSet. It is implemented as a hash table with a linked list running through it, so it provides the order of insertion. The time complexity of basic methods is O(1). 理解: HashSet是通过哈希表来实现的.所有元素无序.增删改查操作的时间复杂度都为O(1...

java.util.LinkedHashSet 类的equals() 方法用于比较指定对象和这个集合是否相等。当且仅当指定的对象也是一个集合,两个集合具有相同的大小,并且两个集合中所有对应的元素对都相等时,返回真。(如果(e1==null ? e2==null : e1.equals(e2)),两个元素e1和e2是相等的)。换句话说,如果两个集合以任何顺序包含...
