    My problem is :

    I execute an exe file from java using the runtime.getRuntime() ,

    But my problem is that the exe is running in the background , and I want when I run my program it opens that exe so I can see what's happening

    anyone got any ideas?

    thanks in advance

    I cant understand your question. Can you be little more specific? or PM me !!


    You can run .exe files using this piece of code 

    Runtime rt = Runtime.getRuntime();
try {
rt.exec(Path:\\TheFile.exe);
} catch (IOException e) {
e.printStackTrace();
}

    You can't actually see the program running but you can capture any System.out's that it may have.

    
Runtime systemShell = Runtime.getRuntime();
Process output = systemShell.exec("<PATH TO EXE>");

// open reader to get output from process
BufferedReader br = new BufferedReader (new InputStreamReader(output.getInputStream()));
String line = null;

while((line = br.readLine()) != null ) {
[INDENT]if(line.length()!=0)[/INDENT]
[INDENT][INDENT]System.out.println(line);	// display process output  [/INDENT][/INDENT]
}          

int exitVal = output.waitFor();             // get process exit value
if(exitVal==0) 
[INDENT]System.out.println("GOOD STATUS");[/INDENT]
else 
[INDENT]System.out.println("BAD STATUS");[/INDENT]
    Code (markup):
