I have briefly listed the performance issues related to trigonometric functions, floating point arithmetic functions and Java Native Interface. I hope these will be helpful.
In Java, results got from trigonometric functions and calculations may not be as accurate as that of results got from trigonometric functions and calculations of C language. This is because because Java has strict specifications for the results of mathematical operations.This
JNI (Java Native Interface) is a powerful feature that provides the developers to call legacy code written in C/C++ and Java. In the post, I will briefly introduce how JNI helps us in doing so.
First step is to create a Java class that declares native method. Native methodís signature contains keyword native and it indicates that this method is implemented in another language. Native method declaration is terminated with a semicolon. Also note that native method does not contain implementation.
