4. Install java JDK:
sudo apt-get install oracle-java8-installer
5. Check the java version to see if the installation is successful:
java -version
2. Oracle JDK version introduction
Oracle JDK is more stable than OpenJDK. The code of OpenJDK and Oracle JDK is almost the same, but Oracle JDK has more classes and some bug fixes. So, if you want to develop enterprise/commercial software, I recommend you to choose Oracle JDK as it is thoroughly tested and stable. In some cases, some people mentioned that they may have encountered many application crashes when using OpenJDK, but simply switching to Oracle JDK can solve the problem.

How to understand DMA operations in C?
Apr 28, 2025 pm 10:09 PM
DMA in C refers to DirectMemoryAccess, a direct memory access technology, allowing hardware devices to directly transmit data to memory without CPU intervention. 1) DMA operation is highly dependent on hardware devices and drivers, and the implementation method varies from system to system. 2) Direct access to memory may bring security risks, and the correctness and security of the code must be ensured. 3) DMA can improve performance, but improper use may lead to degradation of system performance. Through practice and learning, we can master the skills of using DMA and maximize its effectiveness in scenarios such as high-speed data transmission and real-time signal processing.
