SPI(Service Provider Interface),是JDK内置的一种服务提供发现机制,可以用来启用框架扩展和替换组件,主要是被框架的开发人员使用,比如java.sql.Driver接口,其他不同厂商可以针对同一接口做出不同的实现,MySQL和PostgreSQL都有不同的实现提供给用户,而Java的SPI机制可以为某个接口寻找服务实现。Java中SPI机制主要思想是将...

Finds and returns the relative index of the first mismatch between two Object arrays over the specified ranges, otherwise return -1 if no mismatch is found. Mismatch(Single[], Int32, Int32, Single[], Int32, Int32) Finds and returns the relative index of the first mismatch between two ...
this has a significant impact on space consumption -- saving approximately eight percent in heap size for typical applications. The first header word contains information such as the identity hash code and GC status information. The second is a reference to the object's class. Only arrays have ...

Returns a hash code based on the "deep contents" of the specified array. If the array contains other arrays as elements, the hash code is based on their contents and so on, ad infinitum. It is therefore unacceptable to invoke this method on an array that contains itself as an element, ...
