java Socket 通信一

1.首先建立服务端

public class ClientTest {
private static final String host = "192.168.88.103";


public static void main(String[] args) {
BufferedReader br = null;
PrintWriter pw = null;
try {
Socket socket = new Socket(host, ServerTest.PORT);
br = new BufferedReader(new InputStreamReader(
socket.getInputStream()));
pw = new PrintWriter(new BufferedWriter(new OutputStreamWriter(
socket.getOutputStream())));
for (int i = 0; i < 5; i++) {
pw.println("在吗?" + i);
pw.flush();
}
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
pw.close();
br.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}

2.建立客户端

public class ClientTest {
private static final String host = "";  // 自己的主机域名


public static void main(String[] args) {
BufferedReader br = null;
PrintWriter pw = null;
try {
Socket socket = new Socket(host, ServerTest.PORT);
br = new BufferedReader(new InputStreamReader(
socket.getInputStream()));
pw = new PrintWriter(new BufferedWriter(new OutputStreamWriter(
socket.getOutputStream())));
for (int i = 0; i < 5; i++) {
pw.println("在吗?" + i);
pw.flush();
}
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
pw.close();
br.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
