The System#getenv() can offer you specific CPU and OS information. The System#getProperty() can offer you specific OS information. The java.io.File API can offer you global disk information. The only what's missing in the standard API is the OS-level memory information and the other hardware components and peripherals (graphics card, network card, etc).You can consider using JNI to call some 3rd party libraries which can give more detailed information, e.g. Win32 API, but that's operating system dependent - which on its turn you can determine by System#getenv() and #getProperty().好像确实是不可以得到硬件方面的信息，除非你用c/c++.
很不错的图形界面
