服务器端代码：
package exp;
import java.io.*;
import java.net.*;
public class Service {
public static void main(String [] args){
ServerSocket server=null;
Socket you=null;
String s=null;
DataInputStream in=null;
DataOutputStream out=null;
try{
server=new ServerSocket(4331);
}catch(IOException e1){ System.out.println(e1);}
try{System.out.println("等待客户呼叫");
you=server.accept();
out=new DataOutputStream(you.getOutputStream());
in=new DataInputStream(you.getInputStream());
while(true)
{
s=in.readUTF();
int m=Integer.parseInt(s);
out.writeUTF("你好：我是服务器");
out.writeUTF("你说的数乘2后是:"+2*m);
System.out.println("服务器收到:"+s);
Thread.sleep(2000);
}
}catch(Exception e){
System.out.println("客户已断开");
}
}
}
客户端代码：
package exp;
import java.io.*;
import java.net.*;
public class Client {
public static void main(String[] args) {
String s=null;
Socket mysocket;
DataInputStream in=null;
DataOutputStream out=null;
try{
mysocket=new Socket("127.0.0.1",4331);
in=new DataInputStream(mysocket.getInputStream());
out=new DataOutputStream(mysocket.getOutputStream());
for(int k=1;k<100;k=k+2){
out.writeUTF(""+k);
s=in.readUTF();
System.out.println("客户收到:"+s);
Thread.sleep(2000);
}
}catch(Exception e){ System.out.println("服务器已断开"+e);
}
}
}
不明白，白度我
