Java Development Kit (JDK) does not provide a built-in API for camera access. A common workaround is to use OpenCV with Java bindings (such as JavaCV). However, OpenCV is a fairly large library, which may not be suitable for all applications. In this tutorial, we will demonstrate how to build...

Java Native Interface (JNI) is the glue between Java and native code such as C, C++, and assembly. With JNI, Java applications are capable of supporting platform-specific features. JNI enables developers to call low-level APIs (e.g. SQL, OpenGL etc.) to make Java application more powerful with higher performance. For example, we can...
