如何连接到节点客户端及android穿戴操作系统中以下代码等效方法

const net = require('net');

const serverHost = '服务器主机地址';
const serverPort = 8080;

const client = new net.Socket();

client.connect(serverPort, serverHost, () => {
  console.log('已连接到服务器');
});

client.on('data', (data) => {
  console.log('接收到服务器数据：', data.toString());
});

client.on('close', () => {
  console.log('与服务器的连接已关闭');
});

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;

public class Client {
    private static final String SERVER_HOST = "服务器主机地址";
    private static final int SERVER_PORT = 8080;

    public static void main(String[] args) {
        try {
            Socket socket = new Socket(SERVER_HOST, SERVER_PORT);

            BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            PrintWriter out = new PrintWriter(socket.getOutputStream(), true);

            // 发送数据到服务器
            out.println("Hello, server!");

            // 接收服务器返回的数据
            String response = in.readLine();
            System.out.println("接收到服务器数据：" + response);

            // 关闭连接
            socket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
