HashCode() is explicitly used in methods where hash functions are used, like hashTable() etc. One should always override hashCode() when overriding equals(). Unexpected behaviour will occur if you don't do so.
hash方法javajavahashsethashcode equals()跟hashcode()都可以用来比较对象。hashcode通过不同对象有不同的散列码来比较两个对象。hashcode方法把对象放到一个对象容器进行查找,算法好坏直接影响容器的存取效率。 HashCode() is explicitly used in methods where hash functions are used, like hashTable() etc. One s...

1、实现了java.util.Set接口,内部由java.util.Map示例实现(允许null值) 2、不保证迭代顺序,也不保证迭代顺序一直不变 3、非同步;必须从外部同步,比如:Set s = Collections.synchronizedSet(new HashSet()); 4、iterator()返回的iterator是fail-fast的:如果这个iterator创建以后,这个set被修改了(不是这个iterator的...

Provides all functions as IteratorWithKey, but can also be used for reverse iteration. Typical usage of iteration in reverse: it := tree.Iterator() for it.End(); it.Prev(); { key, value := it.Key(), it.Value() ... } Other usages: if it.Last() { lastKey, lastValue := it....

java集合:HashSet和HashMap简述 HashSet底层实际上是一个HashMap HashSet的特点是无序、不可重复。 而HashMap中的key也是无序不可重复的。 因此可以理解为“HashSet就相当于HashMap中的Key部分。HashSet有什么特点,HashMap中的Key就有什么特点。 HashMap底层就是一个哈希表/散列表 哈希表是数组和单向链表的结合...
