Default GUI chat room


i have to do the following:
write a Java program to implement the GUI for a chat program.The program should include components attached to a form: a text field, a pop-up choice-group and up to 8 string items which will be messages entered by the user. Users should be presented with two
commands, ‘Send’ and ‘Exit’.
Beneath the text field and user selection choice-group, there should always be no more than 8 string items, also identifying which user wrote which message. When a message is added to the group of messages, the text field should be erased ready for the next message. After 8 messages have been added to the group of messages, any additional messages are added to the end of the group and the first (oldest) message is removed. Another way to describe this is to
display only the last 8 messages entered.

Any ideas how to do this

I was able to do the part where the user is asked to enter the message and also i did the pop group choice option. But i am not able to get the SEND and EXIT commands to work.
Also how will i get the program to only register the last 8 messages and deletes the rest?

This is the code that i did so far.
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeExcepti on;
import javax.microedition.lcdui.*;

public class MyOwnGUI extends MIDlet {

Display display=Display.getDisplay(this);

public MyOwnGUI() {


protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
// TODO Auto-generated method stub


protected void pauseApp() {
// TODO Auto-generated method stub


protected void startApp() throws MIDletStateChangeException {

// TODO Auto-generated method stub
Form form = new Form("Chat GUI");

//command options
TextField textfield =new TextField("TEXT FIELD","",25,TextField.ANY);

ChoiceGroup CoursePOP = new ChoiceGroup ("Select user", Choice.POPUP,new String[] {"USER A", "USER B"}, null);

Send a message via Yahoo to jalaklenteng

can someone help me solve this problem?!?

This project consists of writing a Java application that sorts input data.
The program will perform the following steps:
Step 1. Read input from a screen – using GUI
Step 2. Sort the input. For example, if the input is a sequence (11,44,33,55,22), and descending order is selected then the sorted sequence will be (55,44,33,22,11). The user can choose either to sort in descending or ascending order.
For example, if the input sequence is
  4 2 9 3 5 6 7 8 10 11 1 12 14 13
then the screen will display the following information:
Data Structure: Array / Linked Chain
Sorting Algorithm: (whatever algorithm – taught in class)
Order : Ascending / Descending
Numbers Read In: 14

Input Sequence:
     4 2 9 3 5 6 7 8 10 11
     1 12 14 13

Sorted Sequence:
    14 13 12 11 10 9 8 7 6 5
     4 3 2 1
