下面的代码只能实现服务端和客户端你一句我一句聊天,要是有一方连续发几条消息就会崩溃,请问如何实现连续发消息这个功能,老师说要用到线程,求提供一点思路
客户端
import java.io.*;
import java.net.*;
public class SingleTalkClient
{
public static void main(String[] args) throws IOException
{
Socket client = null;
PrintWriter out = null;
BufferedReader in = null;
try {
client = new Socket("172.16.122.27", 6677);
out = new PrintWriter(client.getOutputStream(), true); //auto flush
in = new BufferedReader(new InputStreamReader(client.getInputStream()));
} catch (UnknownHostException e) {
System.err.println("Don't know about host: 127.0.0.1.");
System.exit(1);
} catch (IOException e) {
System.err.println("Couldn't get I/O for the connection to: 127.0.0.1.");
System.exit(1);
}
//从标准输入流(键盘)中获取信息
BufferedReader stdIn = new BufferedReader(new InputStreamReader(System.in));
String fromServer, fromUser;
boolean sbye = false;
boolean ubye = false;
System.out.print("Client input:");
fromUser = stdIn.readLine();
while( true )
{
if( ubye == false )
{
out.println(fromUser);
out.flush();
//System.out.println("Client: " + fromUser);
if (fromUser.equals("Bye."))
ubye = true;
}
if( sbye == false )
{
fromServer = in.readLine();
System.out.println("from Server: " + fromServer);
if (fromServer.equals("Bye."))
sbye = true;
}
if( ubye == false )
{
System.out.print("Client input:");
fromUser = stdIn.readLine();
}
if( ubye == true && sbye == true )
break;
}
out.close();
in.close();
stdIn.close();
client.close();
}
}
服务端
import java.net.*;
import java.io.*;
public class SingleTalkServer
{
public static void main(String[] args) throws IOException
{
ServerSocket serverSocket = null;
try {
serverSocket = new ServerSocket(6677);
} catch (IOException e) {
System.err.println("Could not listen on port: 4444.");
System.exit(1);
}
Socket clientSocket = null;
try {
clientSocket = serverSocket.accept(); //程序将在此等候客户端的连接
} catch (IOException e) {
System.err.println("Accept failed.");
System.exit(1);
}
System.out.println("Accept OK!");
//打开输入/输出流
PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true); //auto flush
BufferedReader in = new BufferedReader(
new InputStreamReader(
clientSocket.getInputStream()));
//从标准输入流(键盘)中获取信息
BufferedReader sin = new BufferedReader( new InputStreamReader( System.in ) );
boolean sinbye = false;
boolean inbye = false;
String sinputLine, inputLine;
inputLine = in.readLine();
System.out.println( "from Client: " + inputLine );
System.out.print("Server input:");
sinputLine = sin.readLine();
while( true )
{
if( sinbye == false )
{
out.println(sinputLine);
out.flush();
//System.out.println("Server: " + sinputLine);
if (sinputLine.equals("Bye."))
sinbye = true;
}
if( inbye == false )
{
inputLine = in.readLine();
System.out.println( "from Client: " + inputLine );
if (inputLine.equals("Bye."))
inbye = true;
}
if( sinbye == false )
{
System.out.print("Server input:");
sinputLine = sin.readLine();
}
if( sinbye == true && inbye == true )
break;
}
out.close();
in.close();
sin.close();
clientSocket.close();
serverSocket.close();
}
}
