A map is a special type of collection that stores data in key-value pairs. These are also known as hashtables. The keys that are used to extract the value should be unique. You can create a mutable as well as an immutable map in Scala. The immutable version is inbuilt but mutable ...
passing it original hashMap and then pass this new instance of HashMap to Collecitons.unmodifiableMap() method.The “unmodifiableMap2” that we get here is immutable such that even if you make changes in the original hashmap, it will not reflect in the unmodifiableMap2 instance. ...

HashMap中indexFor方法解析 最近在准备面试,所以重新看了下HashMap的源码,在put方法中计算数组下标值index的indexFor()方法: h & (length-1):其中h为key用hash()算法算出的哈希值,length为数组的长度,且length总是为2的n次幂。 这个计算我一直不能理解,找了一些资料发现都说 h & (length-1)的结果和 h.....
