Password encripting

[Gopal krushna Das]

Hello,
I want to hardcode to the password field. Please help me for that.
I am enclosing my code here.

import com.jscape.inet.ftp.*;
import java.io.*;
import java.util.Enumeration;
 
public class FtpMuploadExample extends FtpAdapter {
    private String hostname;
    private String username;
    private String password;
    
    // perform multiple file upload
    public void doUpload(String hostname, String username, String password) throws FtpException {
        Ftp ftp = new Ftp(hostname,username,password);
        
        //capture Ftp related events
        ftp.addFtpListener(this);
        ftp.connect();
        ftp.setBinary();
        ftp.mupload(".*\\MUT*.*");
        ftp.disconnect();
    }
    
    // captures upload event
    public void upload(FtpUploadEvent evt) {
        System.out.println("Uploaded file: " + evt.getFilename());
    }
    
    // captures connect event
    public void connected(FtpConnectedEvent evt) {
        System.out.println("Connected to server: " + evt.getHostname());
    }
    
    // captures disconnect event
    public void disconnected(FtpDisconnectedEvent evt) {
        System.out.println("Disconnected from server: " + evt.getHostname());
    }
    
    
    public static void main(String[] args) {
        String hostname ;
        String username;
        String password;
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
            System.out.print("Enter Ftp hostname : ");
            hostname = reader.readLine().trim();
            System.out.print("Enter username : ");
            username = reader.readLine().trim();
            System.out.print("Enter password : ");
            password = reader.readLine().trim();
            System.out.println("Using upload filter .*\\MUT*.*");
            FtpMuploadExample example = new FtpMuploadExample();
            example.doUpload(hostname,username,password);
        }
        catch(Exception e) {
            e.printStackTrace();
        }
    }
}

What do you mean by hardcode? If you don't want the user to enter a password, then don't let him enter it. You can use a String constant instead.

As an aside, having two sets of fields called username/password/hostname is bound to cause trouble at some point. Consider removing one of them.

Do you mean when you type the password in the command line you want it to appear as *****?

Please change in my code.

No. People here won't (and SHOULDN'T) do your work for you.

folks around here will bend over backwards to HELP YOU LEARN, and figure it out yourself. they'll point you in the right direction, give you tips and suggestions, make subtle corrections...

if you want somebody to write your code for you, i suggest you post under "jobs offered" and provide decent compensation.

otherwise... if you are having the user input the password from the command line, there's not much you can do (That i'm aware of). it's an OS problem, not a java problem.

you could create a pop-up type window for entering a password - java supports the "*"s for that.

Or use java.io.Console - available through System.console() since Java 6.

Keep in mind that System.console() will return null if no console is available, for instance when run from an IDE.
