我在客户端工作的添加功能请协助修复

Question

服务器端方法用sql添加动物名称，spcies id，动物描述到ms访问数据库

//declarations
private int port;
Socket soc;     //client socket
ServerSocket lstn;      //server socket 
InputStream in;
DataInputStream inData;
OutputStream out;
DataOutputStream outData;
static String client, username, password, request;
boolean connected;
static String model;
static Connection conn;
static Statement st;
static ResultSet rec;

//login 
static String[] ConnectOptionNames = {"Connect", "Cancel"};
static String ConnectTitle = "Set hostname";
//database and sockets
boolean isConnect;
boolean connected;

private void startServer() {

    try {
        lstn = new ServerSocket(port);
        txtWin.append("Listening on port number: " + port + "\n");

        soc = lstn.accept();
        connected = true;

        in = soc.getInputStream();
        inData = new DataInputStream(in);

        out = soc.getOutputStream();
        outData = new DataOutputStream(out);

        client = inData.readUTF();
        etc...(the rest of this code is socket close and catch statements

        txtWin.append("Connection established with " + client + "\n");
        while (connected) {
            model = "";
            txtWin.append("Awaiting new request");
            request = inData.readUTF();
            txtWin.append("Request from client: \t" + request + "\n");


    //add to Animal Table methode server side
    public boolean addAnimal(String name, String desc, int ID) {
    try {
        boolean match = Pattern.matches("[a-z]+", name);
        int count = 0;
        boolean act = false;

        if (match) /*No numbers are allowed in the animal name*/ {
            connectDb();
            java.sql.Statement stmt = conn.createStatement();

            String sql1 = "SELECT * FROM Animals";
            ResultSet rs1 = stmt.executeQuery(sql1);

            while (rs1.next()) {
                count = Integer.parseInt(rs1.getString(1));
            }

            //Check to see if the Species_ID exists
            String sql2 = "SELECT * FROM Species WHERE species_id= " + ID;
            ResultSet rs = stmt.executeQuery(sql2);
            while (rs.next()) {
                String sql3 = "INSERT INTO Animals (animal_id, animal_name, description, species_id) VALUES (" + ++count + ", '" + name + "', '" + desc + "', " + ID + ")";
                int rs2 = stmt.executeUpdate(sql3);
                return true;
            }
            return act;
        } else {
            return act;
        }

    } catch (SQLException e) {
        System.out.println("Server, addAnimal: " + e);
        connected = false;
        return false;
    }
}

***上面是我的应用程序服务器端这个函数是为了从客户端添加3个字符串到ms访问数据库。从名为delegate的switch case调用此方法。它工作正常!!!

接下来是客户端，我发现添加动物错误无效。***
