Getting System Hardware Information Using Java (only windows)

Save your precious data

After searching on the web I found that there is no any pure Java code to get all system hardware information. Although we can get some system details using Java like processor, system architecture and the number of processors using the code below:-

System.out.println(System.getenv("PROCESSOR_IDENTIFIER")); System.out.println(System.getenv("PROCESSOR_ARCHITECTURE")); System.out.println(System.getenv("PROCESSOR_ARCHITEW6432")); System.out.println(System.getenv("NUMBER_OF_PROCESSORS"));

 But beyond this if we want all hardware associated to system like hard disk, RAM, CD/DVD W/ROM network card, BIOS, monitor and other. Then there is no direct code like mentioned above is not available. Either you have to use some third party API or windows tools to get system information.

Using other APIs is sometimes complex to use in our code and configuration is not easy. You can use API like SIGAR which I have heard most.
You can visit it here and can download from here.
But it is also limited.

 In the second approach, you can use windows tool in your Java program to get detailed information of system hardware, which is known as WMIC(Windows Management Instrumentation Command-line).
The sample code is given below to get some system hardware and software information.

String[][] commands = new String[][]
{
 {"CMD", "/C", "WMIC OS GET Installdate,SerialNumber"},
 //OS Installation date & Time, OS Serial Number
 {"CMD", "/C", "WMIC BASEBOARD GET SerialNumber"},
 // Motherboadrd Serial Number 
 {"CMD", "/C", "WMIC CPU GET ProcessorId"}, 
// Processor ID 
 {"CMD", "/C", "WMIC COMPUTERSYSTEM GET Name"},
// Computer Name
 {"CMD", "/C", "WMIC diskdrive GET Name, Manufacturer, Model, InterfaceType, MediaLoaded, MediaType"},
//HDD Details 
 {"CMD", "/C", "WMIC memphysical GET Manufacturer, Model, SerialNumber, MaxCapacity, MemoryDevices"}, 
 }; 

 for (int i = 0; i < commands.length; i++)
 {

 String[] com = commands[i];
 Process process = Runtime.getRuntime().exec(com);
 process.getOutputStream().close();
 //Closing output stream of the process
 System.out.println();
 String s = null;
 //Reading sucessful output of the command
 BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream())); 

 while ((s = reader.readLine()) != null) 
{ 
 System.out.print(s);
 }

 // Reading error if any 
 reader = new BufferedReader(new InputStreamReader(process.getErrorStream()));

 while ((s = reader.readLine()) != null)
 { 
 System.out.print(s); 
 }

 }
