Stream-Mode Sockets

Question

Hi, I am working through a pradtice paper. I need to learn something for tomorrows exam.
Here is the Question
2b) Write detailed Java pseudo code fragments using stream-mode sockets. The code should reflect the following scenario:
•     the server listens on a particular socket
•     the client requests for a connection;
•     the server accepts the connection request;
•     the server sends the message “Send me a line of text” to the client;
•     the client receives the message;
•     The client sends the string “here is a line of text.”
•     The server receives the line
•     The server changes the text into upper case
•     The server sends the changed text back.
•     The client receives the changed text.
Although your code does not need to be syntactically correct, it needs to be detailed enough to show the correct understanding of how the host addresses and port numbers are related to the sockets; it needs to show the correct use of classes and methods.
So Far I have found thins:
Client:
package NetworkProgramming;
import java.io.*;
import java.net.*;
public class Client2 {
public static void main(String[] args) throws Exception {
Client2 myCli = new Client2();
myCli.run();
public void run() throws Exception {
Socket mySkt = new Socket("localhost", 9999);
PrintStream myPS = new PrintStream(mySkt.getOutputStream());
myPS.println("Hello Server");
BufferedReader myBR = new BufferedReader(new InputStreamReader(mySkt.getInputStream()));
String temp = myBR.readLine();
System.out.println(temp);
Server:
package NetworkProgramming;
import java.io.*;
import java.net.*;
public class Server2 {
public static void main(String[] args) throws Exception {
Server2 myServ = new Server2();
myServ.run();
public void run() throws Exception {
ServerSocket mySS = new ServerSocket(9999);
Socket SS_accept = mySS.accept();
BufferedReader SS_BR = new BufferedReader(new InputStreamReader(SS_accept.getInputStream()));
String temp = SS_BR.readLine();
System.out.println(temp);
if (temp != null) {
PrintStream SSPS = new PrintStream(SS_accept.getOutputStream());
SSPS.println("got Something");
Is this the right stuff?
How can i implement the parts in the question into this. like the sending messages, change to upper case etc.
Many thanks for your help.

1. When posting code, use code tags so it will be readable: http://forums.oracle.com/forums/ann.jspa?annID=1429
2. You'll find you get better responses if you ask a more specific question and show your attempt to solve the problem yourself, as opposed to just pasting your assignment and some code you "found" and then asking, "How do I do the rest of this?"
