The method of Java calling cmd command and executing EXE program in Windows system _java

Java invokes the CMD command and outputs display information:

Package com.anxin.cmd.test; 
 
Import Java.io.BufferedReader; 
Import Java.io.InputStreamReader; 

public class Command {public 
 
 static void Main (string[] args) { 
  try { 
   Runtime RT = Runtime.getruntime (); 
   Process PR = rt.exec ("cmd/c dir"); CMD/C Calc 
   //Process PR = rt.exec ("d:\\xunlei\\project.aspx"); 
 
   BufferedReader input = new BufferedReader (New InputStreamReader (Pr.getinputstream (), "GBK")); 
 
   String line = null; 
 
   while (line = Input.readline ())!= null) { 
    System.out.println (line); 
 
   int exitval = Pr.waitfor (); 
   System.out.println ("Exited with error code" + exitval); 
 
  } catch (Exception e) { 
   System.out.println (e.tostring ()); 
   E.printstacktrace ();}} 
 

Three ways to start the native application exe in Java:

The first way: the use of CMD method

/** 
 * Execute cmd command 
 * 
 @param command 
 * @throws ioexception 
 /public 
static String Executecmd ( String command) throws IOException { 
 log.info ("Execute command:" + command); 
 Runtime Runtime = Runtime.getruntime (); 
 Process process = Runtime.exec ("cmd/c" + command); 
 BufferedReader br = new BufferedReader (New InputStreamReader (Process.getinputstream (), "UTF-8")); 
 String line = null; 
 StringBuilder build = new StringBuilder (); 
 while (line = Br.readline ())!= null) { 
  log.info (line); 
  Build.append (line); 
 return build.tostring (); 
} 
 
Executecmd (Start "Axadwebbrowser" "D:\AXAdsBrowser\AXAdWebBrowser.exe"); 

The second way: using Processbuilder to invoke the Cmd method

/** * 
 Start Application 
 * 
 * @param programname 
 * @return 
 * @throws ioexception/public 
static void StartProgram (String programpath) throws IOException { 
 log.info ("Launch application:" + Programpath); 
 if (Stringutils.isnotblank (Programpath)) { 
  try { 
   String programname = programpath.substring ( Programpath.lastindexof ("/") + 1, Programpath.lastindexof (".")); 
   list<string> list = new arraylist<string> (); 
   List.add ("cmd.exe"); 
   List.add ("/C"); 
   List.add ("Start"); 
   List.add ("\" "+ ProgramName +" ""); 
   List.add ("\" "+ Programpath +" ""); 
   Processbuilder Pbuilder = new Processbuilder (list); 
   Pbuilder.start (); 
  } catch (Exception e) { 
   e.printstacktrace (); 
   Log.error ("app:" + Programpath + "does not exist!) "); 
  } 
 } 
} 

The third way: Start the application with desktop

/** * 
 Start Application 
 * 
 * @param programname 
 * @return 
 * @throws ioexception/public 
static void StartProgram (String programpath) throws IOException { 
 log.info ("Launch application:" + Programpath); 
 if (Stringutils.isnotblank (Programpath)) { 
  try { 
   desktop.getdesktop (). Open (New File (Programpath)); 
  catch (Exception e) { 
   e.printstacktrace (); 
   Log.error ("app:" + Programpath + "does not exist!) "); 
  } 
 }
