❤️ Click here: Chat application in java with gui
This is something we will need if we want to have computers communicating each other. When multiple clients connect to one server, we have a simple chat system. MouseEvent evt btnConnectMouseClicked evt ; } ; btnDisconnect.
ActionEvent evt { if SocketManager. Have a good day. MouseAdapter { public void mouseClicked java. I would suggest moving that to that method instead ; ChatServer I didn't make to much of change to this, but just in case...
- Type the following code for the class StartServer import java. MouseAdapter public void mouseClicked java.
I am doing a Chat Application using Java and Swing class for GUI. The ChatServer class will be the server receiving message from clients and echo back to all clients but I only intend to make the chat for 2 clients. The ChatClient class is both of the client. They display what was sent from the server on the Text Area. And send texts in the Text Field to the server. ChatClient Class package chatclient; import java. InputStreamReader; public class ChatClient extends javax. JTextField ; setDefaultCloseOperation javax. MouseAdapter public void mouseClicked java. MouseEvent evt btnConnectMouseClicked evt ; ; btnDisconnect. ActionListener public void actionPerformed java. ActionEvent evt btnDisconnectActionPerformed evt ; ; lblStatus. Color 255, 51, 51 ; lblShowStatus. ActionListener public void actionPerformed java. ActionEvent evt txtInputActionPerformed evt ; ; javax. GroupLayout getContentPane ; getContentPane. Color 0, 204, 51 ; lblShowStatus. Color 255, 51, 51 ; lblShowStatus. LookAndFeelInfo info : javax. SEVERE, null, ex ; catch InstantiationException ex java. SEVERE, null, ex ; catch IllegalAccessException ex java. SEVERE, null, ex ; catch javax. UnsupportedLookAndFeelException ex { java. JButton btnConnect; private javax. JButton btnDisconnect; private javax. JLabel lblShowStatus; private javax. JLabel lblStatus; private javax. JScrollPane scrollPane; private static javax. JTextArea textArea; private javax. The basic problem is, textArea is null when you try and call updateTextArea, this is because the invokeLater call hasn't executed yet and constructed your UI, you basically have a race condition. The normal way to deal with Sockets in Swing is, is to use a SwingWorker Have a look at and for more details. There are a number of ways you could solve you problem. This is good as it de-couples your code and generates a more reusable solution. SocketReader All this class does is reads text from the Socket and generates ActionEvents from the text, simple. Will, very basically, you create an instance of SocketReader and SocketWriter in your ChatClient, you attach an ActionListener to the reader and update the JTextArea when it's triggered and send the text you want sent to the SocketWriter, for example... JTextField ; setDefaultCloseOperation javax. MouseAdapter public void mouseClicked java. MouseEvent evt btnConnectMouseClicked evt ; ; btnDisconnect. ActionListener public void actionPerformed java. ActionEvent evt btnDisconnectActionPerformed evt ; ; lblStatus. Color 255, 51, 51 ; lblShowStatus. ActionListener public void actionPerformed java. ActionEvent evt txtInputActionPerformed evt ; ; javax. GroupLayout getContentPane ; getContentPane. Color 0, 204, 51 ; lblShowStatus. Color 255, 51, 51 ; lblShowStatus. ActionEvent evt if SocketManager. LookAndFeelInfo info : javax. SEVERE, null, ex ; catch InstantiationException ex java. SEVERE, null, ex ; catch IllegalAccessException ex java.
