Executing in java code an external program that takes arguments [duplicate]

Question

Process p;
String line;
String path;
String[] params = new String [3];

params[0] = "D:\\prog.exe";
params[1] = picA+".jpg";
params[2] = picB+".jpg";

try
{
    p = Runtime.getRuntime().exec(params);

    BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));

    while ((line = input.readLine()) != null)
        System.out.println(line);

    input.close();
}
catch (IOException e)
{
    System.out.println(" procccess not read"+e);
}

I don't get any error, just nothing. In cmd.exe prog.exe is working fine.

What to improve in order to make this code working?

Answer 1

Use a p = new ProcessBuilder(params).start(); instead of

p = Runtime.getRuntime().exec(params);

Other than that looks fine.
