Insert response to command from Jsch

Question

I need to run a Unix command from java using Jsch. When I execute this command in the local console of my server, the console shows me a message to insert some parameters:

$ cd /mycinema
$ films
$ Insert the title:

But I do not know how to capture this from java so I can detect that it requires a parameter and be able to insert the title and return the result of the movie without closing the channel or session. Any ideas? My code right now is this (copied from another thread in this forum):

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelExec;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.JSchException;
import com.jcraft.jsch.Session;
import java.io.IOException;
import java.io.InputStream;
import java.io.PrintStream;
import java.util.Properties;

    private Session session;

    private String username = "user";
    private String password = "pass";
    private String hostname = "server";

    public SSHConnectionManager() { }

    public SSHConnectionManager(String hostname, String  , String password) {
        this.hostname = hostname;
        this.username = username;
        this.password = password;
    }

    public void open() throws JSchException {
        open(this.hostname, this.username, this.password);
    }

    public void open(String hostname, String username, String password) throws JSchException{

        JSch jSch = new JSch();

        session = jSch.getSession(username, hostname, 22);
        Properties config = new Properties(); 
        config.put("StrictHostKeyChecking", "no");  // not recommended
        session.setConfig(config);
        session.setPassword(password);

        System.out.println("Connecting SSH to " + hostname + " - Please wait for few seconds... ");
        session.connect();
        System.out.println("Connected!");
    }

        InputStream in = channel.getInputStream(); // channel.getInputStream();

        channel.connect();

        ret = getChannelOutput(channel, in);

        channel.disconnect();
