JSch SFTP upload/download progress

I am new to JSch and Java. I managed to get some code and understand it somehow, but I am stuck on one point. The following code downloads file from SSH/SFTP server, but I am in need of the progress meter that shows percentage of file copied. How can I do it?

import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.SftpProgressMonitor; 
public class SFTPExample {
    public static void main(String args[]) throws Exception {
        String user = "root";
        String password = "password";
        String host = "192.168.0.5";
        int port = 22;
        String knownHostsFilename = "/home/world/.ssh/known_hosts";        
        String sourcePath = "/media/nfs/genotype.txt";
        String destPath = "genotype.txt";        
        JSch jsch = new JSch();
        jsch.setKnownHosts(knownHostsFilename);
        Session session = jsch.getSession(user, host, port);
        session.setPassword(password);
        session.connect(); 
        ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
        sftpChannel.connect();
            
        System.out.println("Downloading test file");
        sftpChannel.get(sourcePath, destPath);            
        
        sftpChannel.exit();
        session.disconnect();
    }
}
