httpconnection在我的java代码中出现奇怪的错误

我写这段代码：

import java.net.HttpURLConnection;
import java.net.URL;
public class Main{
        private static HttpURLConnection connection;
        public static void main(String[] args){
                final URL url = new URL (spec: "https://google.com");
                connection = (HttpURLConnection) url.openConnection();
                connection =url.openConnection();
                connection.setRequestMethod("GET");
                connection.setConnectTimeout(5000);
                connection.setReadTimeout(5000);
                int status = connection.getResponseCode();
                system.out.println(status);
        }
}

并获取以下错误：

Main.java:8: error: ')' expected

我使用OpenJdk：

openjdk version "11.0.6" 2020-01-14
OpenJDK Runtime Environment (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1)
OpenJDK 64-Bit Server VM (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1, mixed mode, sharing)

和UBUNTU 18.04

谢谢您的帮助

这里有一些问题，不是处理异常，而是应该是这样的：

public class Main {
        private static HttpURLConnection connection;
        public static void main(String[] args) throws Exception {
                final URL url = new URL("https://google.com");
                connection = (HttpURLConnection)url.openConnection();
                connection.setRequestMethod("GET");
                connection.setConnectTimeout(5000);
                connection.setReadTimeout(5000);
                int status = connection.getResponseCode();
                System.out.println(status);
        }
}

这个代码应该有效

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;
public class Main{
  private static HttpURLConnection connection;
  public static void main(String[] args) throws IOException {
    final URL url = new URL("https://google.com");
    connection = (HttpURLConnection) url.openConnection();
    connection.setRequestMethod("GET");
    connection.setConnectTimeout(5000);
    connection.setReadTimeout(5000);
    int status = connection.getResponseCode();
    System.out.println(status);
  }
}

我不明白什么是“规范”：IDE提示还是smth？制度也应该来自资本

Main.java:7:错误：'）预期最终URL=新URL（规范：https://google.com");我试试看。它没有帮助终端提出在答案后加括号
