如何下载与安装wordpressseo网络优化推广

我们首先要完成服务端，不然出错，运行也要先运行服务端，如果不先连接服务端，就不监听，那客户端不知道连接谁

服务端

客户端

import javax.swing.JTextArea;
import javax.swing.JTextField;public class KHD extends JFrame implements ActionListener,KeyListener{//1.窗体组件//文本域private JTextArea wby;//滚动条private JScrollPane gdt;//输入面板private JPanel mb;//文本框private JTextField wbk;//按钮private JButton an ;private BufferedWriter BW=null;public KHD() {//将组件初始化wby=new JTextArea();//设置文本域不可编辑wby.setEditable(false);//要将文本域放到滚动条中，实现滚动效果gdt=new JScrollPane(wby);//面板mb=new JPanel();wbk=new JTextField(10);an=new JButton("按钮");//文本框和按钮要放到面板中mb.add(wbk);mb.add(an);//将滚动条和面板放到窗体中this.add(gdt,BorderLayout.CENTER);//将文本内容也就是滚动条放到窗体的中间this.add(mb,BorderLayout.SOUTH);//将输入面板放到窗体的底（南）部//窗体属性setTitle("客户端");//标题setSize(400,400);//窗体大小setLocation(800,200);//位置setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//关闭方式setVisible(true);//是否显示//绑定一个发送的监听事件an.addActionListener(this);wbk.addKeyListener(this);try {//创建客户端的套接字（尝试连接）Socket sk=new Socket("127.0.0.1",8998);//获取Socket的输入流BufferedReader r=new BufferedReader(new InputStreamReader(sk.getInputStream()));//获取Socket的输出流BW=new BufferedWriter(new OutputStreamWriter(sk.getOutputStream()));//循环获取数据，并拼接到文本域中String line=null;while((line=r.readLine())!=null) {//循环读取wby.append(line+"\n");}//关闭Socket通道sk.close();}catch(IOException e) {e.printStackTrace();};}public void sx() {//获取文本框的数据String text=wbk.getText();//拼接要发送的内容text="客户端："+text;//服务端面板显示wby.append(text+"\n");try {//发送BW.write(text);//换行BW.newLine();//刷新BW.flush();//让文本框为空wbk.setText("");}catch(IOException e1) {e1.printStackTrace();}}public static void main(String[]args) {new KHD();}@Overridepublic void actionPerformed(ActionEvent e) {sx();}@Overridepublic void keyPressed(KeyEvent e) {if(e.getKeyCode()==KeyEvent.VK_ENTER) {sx();}}@Overridepublic void keyTyped(KeyEvent e) {// TODO Auto-generated method stub}@Overridepublic void keyReleased(KeyEvent e) {// TODO Auto-generated method stub}}

结果：
