Hello Everyone,

I would like to ask some help from you.
I'm Mark from the Philippines.
I'm a newbie programmer and I'm new with java,that's why it's very difficult for me to make a program using java.

Our Teacher had given us an assignment using java,to make a simple chat window within one week. And that day is on friday,but still I'm not finished doing it.

one text field,one text area,three buttons(Send=to send the text in the text area,Clear=to clear out the text in the text area,Cancel=to cancel the text in the text field). .

The instruction is when you type a message in the textfield then press the send button,the message should appear on the textarea but the problem is when I press the Send button,nothing happens. When I press also the buttons Cancel and Clear,still nothing happens.


Here is my code

import java.awt.*;
import java.awt.event.*;
import java.awt.event.ItemEvent.*;

public class cwindow
    implements ActionListener, ItemListener 
    	{
  private Frame frame;
  private MenuBar menbar;
  private Menu men1;
  private Menu men2;
  private Menu men3;
  private MenuItem meni1;
  private MenuItem meni2;
  private MenuItem meni3;
  private MenuItem meni4;
  private CheckboxMenuItem meni5;
  
  private TextArea txta;
  private Button send = new Button("Send");
  private Button clear = new Button("Clear");
  private Button cancel = new Button("Cancel");
  private TextField marky;

  public void go() 
  	
  	{
    frame = new Frame("chat event");
    menbar = new MenuBar();
    
    txta = new TextArea(" ", 4, 20);
	send.addActionListener(this);
	frame.add(txta, BorderLayout.CENTER);
	marky = new TextField("   ", 25);
	frame.add(send,BorderLayout.EAST);

	marky.addKeyListener( new NameHandler() );
    frame.add(marky, BorderLayout.SOUTH);
    men1 = new Menu("File");
    men2 = new Menu("Edit");
    men3 = new Menu("Help");
    menbar.add(men1);
    menbar.add(men2);
    menbar.setHelpMenu(men3);
    frame.setMenuBar(menbar);

    meni1 = new MenuItem("New");
    meni2 = new MenuItem("Save");
    meni3 = new MenuItem("Load");
    meni4 = new MenuItem("Quit");
    
    meni1.addActionListener(this);
    meni2.addActionListener(this);
    meni3.addActionListener(this);
    meni4.addActionListener(this);
    men1.add(meni1);
    men1.add(meni2);
    men1.add(meni3);
    men1.addSeparator();
    men1.add(meni4);

    meni5 = new CheckboxMenuItem("Persistent");
    meni5.addItemListener(this);
    men1.add(meni5);

    frame.setSize(200,200);
     frame.pack();
    frame.setVisible(true);
   
  }

  public void actionPerformed( ActionEvent ae) {
    System.out.println("Button \"" + 
        ae.getActionCommand() + "\" Pressed.");

    if (ae.getActionCommand().equals("Quit")) {
      System.exit(0);
    }
  }

  public void itemStateChanged(ItemEvent ie) {
    String state = "Deselected";

    if (ie.getStateChange() == ItemEvent.SELECTED) {
      state = "Selected";
    }
    System.out.println(ie.getItem() + " " + state);
  }

 class NameHandler extends KeyAdapter {
    public void keyPressed(KeyEvent e) {
      char c = e.getKeyChar();
      if ( Character.isDigit(c)) {
        e.consume();
      }
    }
  }

  public static void main (String args[]) {
    cwindow markyMenu = new cwindow();
    markyMenu.go();
  }
}

Best regards!

public void actionPerformed( ActionEvent ae) {
String st=marky.getText();
txta.setText(st);


if (ae.getActionCommand().equals("Quit")) {
System.exit(0);
}
}

We don't give people code, we help them learn how to do it themselves. There isn't anything constructive that can come out of you posting that code for him. And the code you posted doesn't match the assignment by a long shot anyway.

First am not post the code
I try to check the his actionlistener and make some change
if I wrong sorry
