谁能教我怎样用java send email????我想不到要怎么做填什么。。。
这个是老师给我的问题：
import java.io.*;
import java.net.*;


public class EmailSender
{

public static void main(String[] args) throws Exception

{

// Establish a TCP connection with the mail server.





// Create a BufferedReader to read a line at a time.

InputStream is = socket.getInputStream();

InputStreamReader isr = new InputStreamReader(is);

BufferedReader br = new BufferedReader(isr);



// Read greeting from the server.

String response = br.readLine();

System.out.println(response);

if (!response.startsWith("220") {


throw new Exception("220 reply not received from server.";

}



// Get a reference to the socket's output stream.

OutputStream os = socket.getOutputStream();



// Send HELO command and get server response.

String command = "HELO alice\r\n";

System.out.print(command);

os.write(command.getBytes("US-ASCII");

response = br.readLine();

System.out.println(response);

if (!response.startsWith("250") {

throw new Exception("250 reply not received from server.";

}



// Send MAIL FROM command.





// Send RCPT TO command.





// Send DATA command.





// Send message data.



// End with line with a single period.





// Send QUIT command.



}
}

这就是run过后的error:

EmailSender.java:13: cannot find symbol
symbol  : variable socket
location: class EmailSender
      InputStream is = socket.getInputStream();
                       ^
EmailSender.java:25: cannot find symbol
symbol  : variable socket
location: class EmailSender
      OutputStream os = socket.getOutputStream();
                        ^
2 errors
