Answer 1

你可以试试 System.getenv()要获取环境变量，请使用 PROCESSOR_ARCHITECTURE 键获取 CPU 架构:

System.out.println(System.getenv("PROCESSOR_ARCHITECTURE"));

或者在 64 位的情况下:

System.out.println(System.getenv("PROCESSOR_ARCHITEW6432"));

另一种方法是使用“os.arch” system property :

System.getProperty("os.arch");

并且您可能需要在使用 System.getProperty("os.name") 之前获取操作系统，因为正如 QMuhammad 在他的回答中提到的那样，这取决于操作系统。

公告that :

System properties and environment variables are both conceptually mappings between names and values. Both mechanisms can be used to pass user-defined information to a Java process.
