1. Introduction At times, it is necessary to use native (non-Java) codes (e.g., C/C++) to overcome the memory management and performance constraints in Java. Java supports native codes via the Java Native Interface (JNI). JNI is difficult, as it inv…
一.什么是java native method? "A native method is a Java method whose implementation is provided by non-java code." 简单来讲Native Method就是java调用非java代码的接口,该方法的实现由非java代码实现,比如C.C++. 定义一个Native Method,并不提供具体的实现体(有点像Java Interface),因为其实现体是非Java代码在外面实现的. pu…
