Java Implementation Operation DOS command

Java implements two ways to operate DOS commands

1. Read the commands in the file

Package Com;import Java.io.inputstream;public class cmd {public        static void Main (string[] args) {        String path = " d:\\cmd.bat";        Runtime run = Runtime.getruntime ();        try {            //run.exec ("cmd/k shutdown-s-T 3600");            Process process = Run.exec ("cmd.exe/k start" + path);            InputStream in = Process.getinputstream ();            while (In.read ()! =-1) {                System.out.println (In.read ());            }            In.close ();            Process.waitfor ();        } catch (Exception e) {            e.printstacktrace ();}}    }

The results of the operation are as follows:

Second way, Direct read command

Package Com;import Java.io.BufferedReader;   Import Java.io.InputStreamReader;  Public classQUMF { Public Static voidMain (string[] args) {Try{Runtime rt=Runtime.getruntime (); Process PR= Rt.exec ("cmd/c Ping www.baidu.com && dir "); //Process PR = rt.exec ("d:\\xunlei\\project.aspx"); BufferedReader input =NewBufferedReader (NewInputStreamReader (Pr.getinputstream (),"GBK")); String Line=NULL;  while(line = Input.readline ())! =NULL) {System. out. println (line); }                intExitval =pr.waitfor (); System. out. println ("Exited with error code"+exitval); } Catch(Exception e) {System. out. println (E.tostring ());          E.printstacktrace (); }      }  }
