A、Collection 接口存储一组不唯一,无序的对象 B、List 接口存储一组不唯一,有序(插入顺序)的对象 C、Set 接口存储一组唯一,无序的对象 二、List接口 1、ArrayList实现了长度可变的数组,在内存中分配连续的空间。遍历元素和随机访问元素的效率比较高 2、LinkedList采用链表存储方式。插入、删除元素时效率比较高 问...

System.out.println(namesIterator.next()); }Copy We can also use theforEachRemainingmethod added in Java 8: namesIterator.forEachRemaining(System.out::println);Copy We can also mix these solutions: StringfirstName=namesIterator.next();// save first name to variablenamesIterator.forEachRemaining(...
