    Default response to the execution of an commande by code java

    hello
    in my java program I excecute a command through the code => it works
    but as I stepped into the prog : I found myself with a command that requires an answer after his execution

    then by java program: I do not know how to answer but in the command line I responds with yes and it works
    do you have any idea how to respond through the java code
    I hope you understand the question:
    Here's the code I use for execute command DOS :
    public static String importer_certificat(String alias,String nom_certi,String nom_keystore,String pass_keystore)
        {
            try{
     
                String b = "keytool -import -alias "+alias+" -file "+nom_certi+" -keystore "+nom_keystore +" -storepass "+pass_keystore;
                System.out.println(b);
                Process p = Runtime.getRuntime().exec(b);
                BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
                String inputLine, tous = "";
                while ((inputLine = in.readLine()) != null)
                {
                    tous += "\n"+inputLine;
                    System.out.println(inputLine);
                } 
                return tous;
     
            }catch(Exception e)
            {
                e.printStackTrace();
                return e.getMessage();
            }
        }
    thank you in advance

    The Process class has methods for getting streams for output from the process and for input to the process. See the API doc
