char是Java中的保留字,与别的语言不同的是,char在Java中是16位的,因为Java用的是Unicode。不过8位的ASCII码包含在Unicode中,是从0~127的。 char在java中是unicode编码,比如字符'a'对应的是97,那么char c2=97,unicode码表中对应的字符! Java中使用Unicode的原因是,Java的Applet允许全世界范围内运行,那它就需要...

这时就有一个加载因子的参数,如果加载因子为0.75 ,如果你hashmap的 空间有 100 那么 当你插入了75个元素的时候 hashmap就需要扩容了,不然的话 会形成很长散列桶 , 对于查询和插入都会增加时间,因为 他要一个一个的equals。 但是你又不能让加载因子很小,0.01 这样是不合适的,因为 他会大大消耗你的 内存, ...
This is a value-based class; programmers should treat instances that are #equals(Object) equal as interchangeable and should not use instances for synchronization, or unpredictable behavior may occur. For example, in a future release, synchronization may fail. --> Added in 1.0. Java documentation...
