只需要实现简单的通信,但是服务器没有提示,怎么改
import java.io.*;
import java.net.*;
class Client{
public static void main(String[] args) {
try {
Socket socket = new Socket("127.0.0.1", 5050);
DataOutputStream out = new DataOutputStream(socket.getOutputStream());
out.writeUTF("我是客户机");//使用UTF-8编码传递字符串
DataInputStream in = new DataInputStream(socket.getInputStream());
String s = in.readUTF();
out.flush();
System.out.println("客户机收到:" + s);
in.close();
out.close();
socket.close();
}
catch (Exception e) {
}
}
}
服务器端代码
import java.io.*;
import java.net.*;
class Server {
public static void main(String[] args) {
try {
ServerSocket s_socket = new ServerSocket(5050);
Socket socket = s_socket.accept();
DataInputStream in = new DataInputStream(socket.getInputStream());
DataOutputStream out = new DataOutputStream(socket.getOutputStream());
boolean goon=true;
String s;
while (goon) {
s = in.readUTF();
if (!s.equals("byte")) {
System.out.println("服务器收到:" + s);
out.writeUTF("我是服务器");
out.flush();
}
else {
goon=false;
out.writeUTF("byte");
out.flush();
}
in.close();
out.close();
s_socket.close();
}
} catch (Exception e) {
}
}
}
运行之后没显示
