TCP:模擬登錄 :雙向

服務器端

public class tcp {

public static void main(String[]args) throws IOException
{
    System.out.println("服務器啟動中...");

    ServerSocket server=new ServerSocket(8888);

    Socket client=server.accept();

    DataInputStream dis=new DataInputStream(client.getInputStream());

    String datas=dis.readUTF();
    String uname="";
    String password="";

    String[] data=datas.split("&");
    System.out.println("用戶名為:"+data[0]+"密碼為:"+data[1]);
    uname=data[0];
    password=data[1];

    //輸出
    DataOutputStream dos= new DataOutputStream(client.getOutputStream());

    if(uname.equals("杜雨龍")&&password.equals("你最帥"))
    {

        dos.writeUTF("登錄成功");
    }else
    {
        dos.writeUTF("登錄失敗");
    }
    dis.close();
    client.close();
    server.close();

}
}

客戶端:

public class tcp2 {

public static void main(String[]args) throws IOException
{
    System.out.println("發送端啟動中");
    BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
    System.out.println("請輸入用戶名");
    String name =br.readLine();
    System.out.println("請輸入密碼");
    String password =br.readLine();

    Socket client=new Socket("localhost",8888);

    DataOutputStream dos= new DataOutputStream(client.getOutputStream());

    dos.writeUTF(name+"&"+password);
    dos.flush();

    DataInputStream dis=new DataInputStream(client.getInputStream());
    String result=dis.readUTF();
    System.out.println(result);

    dos.close();
    client.close();

}
}
