JAVA is a software development language running on virtual machines. It relies on virtual machines to explain bytecode, cleverly implementing cross-platform. JAVA is relatively secure because it is closed. However, external calls are implemented through the JNI dynamic library. Today, we will explain how to develop a JNI dynamic

Univocity-parsers is an open-source Java project. For csv/tsv/fixed-width text file parsing, it provides a rich and powerful function with the Simple API development interface. Further introductions will be made later.Unlike other analytic libraries, Univocity-parsers has designed a set of own architectures based on high performance and scalability. Based on this architecture, developers can build a new file parser.1. OverviewAs a

Preface With the help of CLE, it is easy to use C # dynamic libraries in Java, which is illustrated by a simple example. Using CLE, you need to install the http://www.srplab.com/Data/starcore_win32.2.0.3.exe beforehand.
