Equivalent Scala code for Java code

Question

I am new to scala.Any one having idea what is the equivalent code in scala for the following java code

package sampleFTP
import org.apache.commons.net.ftp.FTPClient
import org.apache.commons.net.ftp.FTPReply;
import org.apache.commons.net.ftp.FTPSClient;
import com.jcraft.jsch._
object FTPTest {



 def main(args: Array[String]) {
      println("Hello, world!")
      var ftpClient= new FTPClient();


    val SFTPPASS = "xxxx";
    val SFTPWORKINGDIR = "/xxxx/xxxx";


    System.out.println("preparing the host information for sftp.");

 val jsch = new JSch();
        var session = jsch.getSession("xxxx", "xxxx", 22)
        session.setPassword(SFTPPASS);
        var config = new java.util.Properties();
        config.put("StrictHostKeyChecking", "no");
        session.setConfig(config);
        session.connect();
        System.out.println("Host connected.");
        var channel = session.openChannel("sftp");
        channel.connect();
        System.out.println("sftp channel opened and connected.");


       var sftpChannel = (ChannelSftp) session.openChannel("sftp");//error in this line
        System.out.println("Directory:" + sftpChannel.pwd());

        session.disconnect();
  }

}

I am getting the following error

value session is not a member of object com.jcraft.jsch.ChannelSftp

I have Successfully implemented the secure FTP connection using jsch.How to download and list file via jsch in scala.

I tried this (var sftpChannel = (ChannelSftp) channel;) also — arun, Jan 23 '17 at 06:06

To cast to a different type in Scala use:

session.openChannel("sftp").asInstanceOf[ChannelSftp]

Note that casting is frowned upon in scala. Pattern matching is usually thought to be better. – irundaia Jan 23 '17 at 10:48
in 2022, please never do this, you should not have in 2017 either, when i first started learning scala. – ekydfejj Sep 18 '22 at 22:48
