public void clear(): Removes all of the elements from this list. The list will be empty after this call returns. Example In this example we have a LinkedList of String type that has 5 elements. We are calling clear() method and displaying the LinkedList elements before and after calling t...
HashSet只存储不同的值,set中是不会出现重复值的。 HashSet和HashMap一样也需要实现hash算法来计算对象的hash值,但不同的是,HashMap中添加一个键值对的时候, (Key, Value),hash函数计算的是Key的hash值。而HashSet则是计算value的hash值。当我们调用HashSet的add(E e)的方法 的时候,我们会计算机元素e的hash...
