java聊天系統(tǒng)代碼 java聊天程序

java的問題，一個(gè)簡(jiǎn)單的聊天程序

lz 你好

專注于為中小企業(yè)提供成都做網(wǎng)站、成都網(wǎng)站建設(shè)服務(wù),電腦端+手機(jī)端+微信端的三站合一,更高效的管理,為中小企業(yè)壽寧免費(fèi)做網(wǎng)站提供優(yōu)質(zhì)的服務(wù)。我們立足成都，凝聚了一批互聯(lián)網(wǎng)行業(yè)人才，有力地推動(dòng)了上1000家企業(yè)的穩(wěn)健成長(zhǎng)，幫助中小企業(yè)通過網(wǎng)站建設(shè)實(shí)現(xiàn)規(guī)模擴(kuò)充和轉(zhuǎn)變。

具體代碼如下:

import?java.awt.*;

import?java.awt.event.*;

import?javax.swing.*;

public?class?Chat?extends?JFrame{

private?JLabel?enter,start;

private?JTextField?input;

private?JTextArea?output;

public?Chat()?{

super("小程序查看器:Client.class");

enter?=?new?JLabel("html小程序brEnter?Text/html");

enter.setFont(new?Font("宋體",?Font.PLAIN,?12));

start?=?new?JLabel("小程序已啟動(dòng)。");

start.setFont(new?Font("宋體",?Font.PLAIN,?12));

input?=?new?JTextField(30);

output?=?new?JTextArea(10,35);

output.setEditable(false);

input.addKeyListener(new?KeyAdapter(){

public?void?keyPressed(KeyEvent?e){

if(e.getKeyCode()?==?10){

output.append(input.getText()?+?"\n");

}

});

setLayout(new?FlowLayout(FlowLayout.LEFT,1,1));

getContentPane().add(enter);

getContentPane().add(input);

getContentPane().add(output);

getContentPane().add(start);

setLocation(300,200);

setSize(450,270);

setResizable(false);

setVisible(true);

setDefaultCloseOperation(3);

}

public?static?void?main(String[]?args)?{
