map.remove() IdentityHashMap 是一个Map的实现类,但是由于他有意违反Map的设计原则,所以不是Map的通用实现,与HashMap属于并列关系,他有个很大的特点,就是key可以存放相同的元素。也可以存放key于value都为null。IdentityHashMap利用哈希表来实现Map接口,比较键(和值)时使用引用相等性代替对象相等性,也就是说使用 ...
(key), key)) == null ?...null : e.value; } get方法的实现就是计算key的hash值,然后通过getNode获取对应的value remove方法 public V remove(Object key) {...null : e.value; } remove方法也是通过计算key的hash,调用removeNode来删除元素的 HashMap的一些特性 允许key和value为null 除了允许为努力...

The test cases are generated such that there are no cycles anywhere in the entire linked structure. Note that the linked lists must retain their original structure after the function returns. Custom Judge: The inputs to the judge are given as follows (your program is not given these inputs)...
