一个完整的Socket例子
服务端的程序:
[code]
import java.io.*;
import java.net.*;
public class SocketServer {
ServerSocket ss=null;
Socket s=null;
DataInputStream inStream=null;
DataOutputStream outStream=null;
public SocketServer() {
try{
init();
}
catch(Exception e){
System.out.println(e.toString());
}
}
void init() throws Exception{
ss=new ServerSocket(765);
s.setSoTimeout(3000);
}
void waitForClient(){
try{
s=ss.accept();
inStream=new DataInputStream(s.getInputStream());
outStream=new DataOutputStream(s.getOutputStream());
outStream.writeUTF("1");
s.setSoTimeout(3000);
waitData();
}
catch(Exception e){
System.out.println(e.toString());
}
}
void waitData(){
while(true){
try{
String str=inStream.readUTF();
System.out.println("Server accept: "+str);
int nu=Integer.parseInt(str)+1;
if(nu>20){
System.out.println("Send end!");
break;
}
else{
str=Integer.toString(nu);
outStream.writeUTF(str);
}
}
catch(Exception e){
System.out.println(e.toString());
break;
}
}
}
public static void main(String[] args) {
SocketServer socketServer1 = new SocketServer();
socketServer1.waitForClient();
}
}
客户端的程序:
import java.net.*;
import java.io.*;
public class SocketClient{
Socket s=null;
DataInputStream inStream=null;
DataOutputStream outStream=null;
public SocketClient() {
try{
init();
waitData();
}
catch(Exception e){
System.out.println(e.toString());
}
}
void init() throws Exception{
s=new Socket("192.168.0.32",765); //把这里的IP改成你运行SocketServer.class的IP
inStream=new DataInputStream(s.getInputStream());
outStream=new DataOutputStream(s.getOutputStream());
s.setSoTimeout(3000);
}
void waitData(){
while(true){
try{
String str=inStream.readUTF();
System.out.println("Client accept: "+str);
str=Integer.toString(Integer.parseInt(str)+1);
outStream.writeUTF(str);
}
catch(Exception e){
System.out.println(e.toString());
break;
}
}
}
public static void main(String[] args) {
SocketClient socketClient1 = new SocketClient();
}
}
