Java memperoleh kode instance informasi dari sistem operasi saat ini

Ada beberapa metode untuk penggunaan utama, satu adalah menggunakan fungsi berikut

publicstaticStringgetProperty(Stringkey)

Salah satunya adalah menggunakan baris perintah untuk mendapatkannya

 Impor java.io.bufferedReader; import java.io.inputstream; impor java.io.inputStreamreader; impor java.net.inputStreamReader; import java.net.intaddress; import java.net.netWorkInderface; impor java.util. java.util.list; import java.util.locale; import java.util.map; import java.util.properties; tes kelas publik {// dapatkan informasi konfigurasi komputer dengan mencegat cmd flow (buruk) Daftar statis = getipaddress () {Proses P = NULL; DAFTAR PUBLIK = PUBLIK = Getipaddress () {Proses P = NULL; ProcessBuilder("ipconfig", "/all").start();}catch (Exception e) {return address;}StringBuffer sb = new StringBuffer();//Read the process output value InputStream inputStream = p.getInputStream();BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));String s = "";try {while ((s = br.readline ())! = null) {sb.append (s + "/n");}} catch (exception e) {e.printstacktrace ();} akhirnya {coba {inputStream.close ();} catch (exception e) {e.printstack (); Alamat pengembalian;} public static void getIpConfig () {peta <string, string> map = system.getEnv (); System.out.println (Map.get ("Username")); // Dapatkan nama pengguna System.out.println (Map.get ("ComputerName"));//Get Computer Name.out.println (Map.get ("Computername")); Nama} // Dapatkan alamat IP komputer dan alamat MAC public static void getConfig () {coba {inetAddress alamat = inetaddress.getLocalHost (); networkInterface ni = networkInterface.getByItAddress (alamat); // ni.getInetAddresses ().
