Object.hashCode() algorithm
hashcode, java, pseudocode
Solution
Native `hashCode` method implementation depends on the `JVM`. By default in HotSpot it returns random number, you can check it in the source code (function `get_next_hash`)
Problem
I'm looking for the algorithm of Object.hashCode(). This code is native in Object.java. Is this because (a) the code is in assembly-- never was in Java or any other HLL at all or (b) it simply isn't disclosed ? In either case, I am looking to get hold of the algorithm (pseudo-code or some detailed explanation) of "how hashCode() is calculated"-- what are the params going into its calculation and the calculation itself? Please note: It's the hashCode() of Object i'm looking for-- not another like that of String or hashMap/table. //========================================================================== the new Java docs-- jdk 8 now saying ``` "The value returned by hashCode() is the object's hash code, which is the object's memory address in hexadecimal." ```
