#How to write the java path in Linux?

In Unix/Linux, paths are separated by forward slash "/", such as "cd /home/java".

Relative path and absolute path

. Refers to the current directory

.. Refers to the upper-level directory of the current directory

./book represents the book folder under the current directory

/book represents the book folder under the current drive letter

Below are some operations for using Java to obtain the path in Linux:

// 分隔符
String fileSeperator = File.separator;

// 用户主目录
String userHome = System.getproperties().getProperty("user.home");

// Java实时运行环境的安装目录
String javaPath = System.getproperties().getProperty("java.home");

// 操作系统名称
String osName = System.getproperties().getProperty("os.name");

// 当前用户程序所在目录
String userDir = System.getproperties().getProperty("user.dir");

// JDK的安装目录
String jdkDir = System.getproperties().getProperty("java.ext.dirs");
Copy after login

How to understand DMA operations in C? 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.
