Game entry to display the top 10 scores in array i have an assignment to change it into linked list without using the build-in classes.(implement).
collection实现了集合的最基本的接口,声明了适应于java集合(set和list)的通用方法 collection接口的方法:(set和list也拥有下面的方法) 1boolean add(Object o) :向集合中加入一个对象的引用2void clear():删除集合中所有的对象,即不再持有这些对象的引用3boolean isEmpty() :判断集合是否为空4boolean contains(Obje...

LinkedHashSet:具有HashSet的查询速度,且内部使用链表维护元素的顺序(插入的次序)。于是在使用迭代器遍历Set时,结果会按元素插入的次序显示。 2.list(列表) List的特征是其元素以线性方式存储,集合中可以存放重复对象。 List接口主要实现类包括:(ArrayList与LinkedList的区别) ...
