Re: How to run external .exe programs from java

the code goes like this:

Java Syntax (Toggle Plain Text)
try
{
 Runtime rt = Rintime.getRuntime() ;
 Process p = rt.exec("Program.exe") ;
 InputStream in = p.getInputStream() ;
 OutputStream out = p.getOutputStream ();
 InputSream err = p,getErrorStram() ;
 
//do whatever you want
 //some more code
 
 p.destroy() ;
}catch(Exception exc){/*handle exception*/}
try
{
 Runtime rt = Rintime.getRuntime() ;
 Process p = rt.exec("Program.exe") ;
 InputStream in = p.getInputStream() ;
 OutputStream out = p.getOutputStream ();
 InputSream err = p,getErrorStram() ;
 
//do whatever you want
 //some more code
 
 p.destroy() ;

Re: How to run external .exe programs from java

try out this code ... it will not be platform independent ....
Process p = Runtime.getRuntime().exec("c:\myprogram.exe");

I dont have the time to test it .... if you succeed please tell me too.

Re: How to run external .exe programs from java

i'm using the code from above to try to run a program and here's my problem... when i call an exe that i wrote in VB, the program runs fine. if i call a c or c++ program the program loads into memory (i see it in the processes tab) but the console doesn't open up with the program in it.
here's the code i have right now for it...

Java Syntax (Toggle Plain Text)
try
   {
    Runtime rt = Runtime.getRuntime();
    Process p = rt.exec("vbex.exe");
    InputStream in = p.getInputStream();
    OutputStream out = p.getOutputStream();
    InputStream err = p.getErrorStream();
 
    p.destroy() ;
    }catch(Exception exc){/*handle exception*/}
try
   {
    Runtime rt = Runtime.getRuntime();
    Process p = rt.exec("vbex.exe");
    InputStream in = p.getInputStream();
    OutputStream out = p.getOutputStream();
    InputStream err = p.getErrorStream();

    p.destroy() ;
    }catch(Exception exc){/*handle exception*/}

Re: How to run external .exe programs from java

hi everyone,

Do this instead

void run ()
{
try
{
Runtime rt = Runtime.getRuntime();
Process p = rt.exec("vbex.exe");
}

catch(Exception e)
{

}

}

I hope this helps you

Re: How to run external .exe programs from java

There are a load of answers in this 2004 zombie thread using Runtime.exec to run an external process, but this was superseded in Java 5 (JDK 1.5) with ProcessBuilder, which is now preferred to Runtime.exec
